Who Is Zoe Grace Quaid?
Zoe was born in Santa Monica on November 8, 2007, via a gestational carrier. Her twin brother, Thomas Boone Quaid, arrived first at 8:26 a.m. Zoe followed two minutes later, weighing 5 pounds, 9 ounces. The twins are the biological children of Dennis and his then-wife, Kimberly.
Her public profile remains limited. Dennis has discussed fatherhood in interviews, but the twins’ daily lives have largely stayed outside celebrity coverage. Many biography sites still present guesses about her height, career, education, and finances as facts.
Zoe Grace Quaid’s Age and Life Now
Zoe Grace Quaid’s age is 18 as of July 2026. She turned 18 on November 8, 2025, and reportedly completed high school in May 2026. People reported, based on her public social media, that she planned to attend the University of Virginia afterward.
It is the strongest current update, although the university has not confirmed her enrollment. She remains a private young adult rather than a celebrity with a documented schedule.
A school senior spotlight stated that she played volleyball throughout high school, including three varsity years, and also played club volleyball. This supports searches about Zoe Grace Quaid volleyball, but no source confirms a college roster position or athletic scholarship.
Her Mother, Kimberly Buffington
Zoe Grace Quaid’s mother is Kimberly Buffington, a real estate professional who was Dennis Quaid’s third wife. The couple married in 2004, welcomed the twins in 2007, and finalized their divorce in 2018. Older coverage often called her Kimberly Quaid, which explains searches combining Kimberly Quaid and Zoe Grace Quaid.
Dennis and Kimberly share Zoe and Thomas. Dennis’s oldest child, Jack, was born during his marriage to Meg Ryan. In May 2026, Dennis asked a Los Angeles court to end monthly child-support payments for the twins after their high school graduations under their 2018 divorce agreement.
The filing concerned a legal support obligation’s stated endpoint, not a reported dispute involving Zoe. Entertainment Weekly reported that the request followed language in the divorce agreement concerning when support eligibility ends.
Her Twin Brother, Thomas Boone Quaid
Thomas Boone Quaid and Zoe Grace Quaid are fraternal twins. Thomas was born two minutes earlier, and both shared the same newborn medical crisis. Reliable coverage does not identify Thomas as an actor or public professional.
Searches for Zoe Grace Quaid twin therefore refer to Thomas, not Jack. Jack is their older paternal half-brother. Available reporting suggests that the twins grew up around fame without being turned into child performers.

The Newborn Hospital Accident
The most serious event in Zoe’s public story happened days after her birth. Zoe and Thomas were admitted to Cedars-Sinai Medical Center in Los Angeles while being treated for staph infections. Hospital staff mistakenly administered heparin at 1,000 times the intended infant dose.
Dennis later testified before Congress that the 12-day-old twins received 10,000 units of heparin twice during an eight-hour period. The overdose prevented their blood from clotting normally and placed them at risk of uncontrolled bleeding. Medical staff used an antidote, and both children recovered.
The Los Angeles Times reported that the parents learned about the error the following morning. State records cited by the newspaper said Zoe had shown bleeding around an intravenous site and her heel. By early December 2007, both twins had left the hospital without a publicly reported lasting injury.
This medication error is what credible results mean by the Zoe Grace Quaid accident. No reliable reporting supports claims that she later experienced a major car crash or another widely reported accident.
Why the Incident Became a Patient-Safety Story
The overdose became a national patient-safety issue after Dennis spoke publicly. In May 2008, he testified at a U.S. House Committee on Oversight and Government Reform hearing about drug labeling, regulation, and patients’ legal rights. The official hearing record identifies Zoe and Thomas as victims of a heparin overdose.
Dennis and Kimberly also supported efforts to raise awareness of preventable medical mistakes. Dennis later participated in patient-safety documentaries and continued discussing medication errors. Zoe herself did not become a public campaigner, so assigning her a formal advocacy role would be inaccurate.
Does Zoe Grace Quaid Act in Movies?
There are no verified Zoe Grace Quaid movies or television credits in reliable reporting. She attended the Los Angeles premiere of Reagan with her father in August 2024, but a red-carpet appearance does not mean she acted in the film. Dennis played President Ronald Reagan in the movie.
The confusion likely comes from her family name. Dennis has a long film career, while Jack Quaid is known for The Hunger Games, The Boys, Scream, and other projects. Current profiles identify Jack, not Zoe, as the actor.
No reliable source has announced that Zoe plans to pursue acting. Any claim about an upcoming film career is currently speculation.
Zoe Grace Quaid and Jack Quaid
Zoe and Jack are paternal half-siblings who share Dennis Quaid as their father. Jack was born in 1992 to Dennis and Meg Ryan, making him more than 15 years older than the twins. He began building his acting career while Zoe and Thomas were still children.
Public posts have shown Jack with the twins, but their private relationship remains largely undocumented. No verified movie, television project, or business partnership connects Zoe Grace Quaid and Jack.
Public Updates From 2023 to 2026
In 2023, Dennis called himself a “dorky dad” and said he was proud of Jack, Thomas, and Zoe. The remarks offered a rare glimpse into his relationship with his teenage children without revealing private details about Zoe’s life.
The clearest Zoe Grace Quaid 2024 event was her appearance with Dennis at the Los Angeles premiere of Reagan on August 20. She attended as his daughter, not as a credited cast member.
In July 2025, Dennis said Zoe was working as a counselor at a Texas summer camp near the region affected by the deadly Hill Country floods. He said her camp was safe after he initially struggled to contact her.
Searches tied to Zoe Grace Quaid 2017 or Zoe Grace Quaid 2019 do not lead to similarly important, independently verified milestones. Publicly indexed material from those periods mainly consists of older family photographs, sightings, and recycled celebrity profiles.
By 2026, reporting described Zoe as an 18-year-old graduate preparing for college. That is the most accurate answer to searches asking where Zoe Grace Quaid is now.
Height, Net Worth, and Other Unverified Claims
Zoe Grace Quaid’s height has not been confirmed by a reliable source. Some celebrity sites publish an exact figure without explaining where it came from. Photographs cannot provide a dependable measurement, so any precise height should be labeled unverified.
There is also no credible estimate of her personal net worth. She has no confirmed entertainment career, public business, endorsement portfolio, or disclosed earnings. Assigning part of Dennis Quaid’s fortune to her would be misleading because a parent’s assets are not the child’s net worth.
No reputable reporting confirms a public romantic partner. Appearance-focused and swimsuit-related searches also offer no useful biographical information, and much of the content attached to them dates from when she was under 18. A factual profile should not turn unsupported or sexualized search terms into claims.
Why Interest in Zoe Grace Quaid Continues
Interest in Zoe comes from her Hollywood family, the newborn medical error she survived, and her recent transition into adulthood. Those facts naturally lead readers to wonder whether she will follow Dennis or Jack into entertainment.
For now, the evidence points elsewhere. Her documented interests include school leadership, volleyball, summer-camp work, and plans for higher education, while her public appearances remain occasional. She may choose a public career later, but her current story is about family, survival, education, and a private upbringing.
