Adrian Grenier (born July 10, 1976) is an American actor, producer, director, musician and environmentalist. He is best known for playing Vincent Chase in the television series Entourage (2004–2011). He has appeared in films such as Drive Me Crazy (1999), The Devil Wears Prada (2006) and Trash Fire (2016).
Grenier was born in Santa Fe, New Mexico, the son of Karesse Grenier and John Dunbar. His parents were never married. He was raised by his mother in New York City. His father was from Ohio, and has English, German, Scottish and Irish ancestry. His mother was born in New Mexico, to a family of mostly Mexican (Indigenous, Spanish) and some French descent.
A DNA test on the series Finding Your Roots showed Grenier to have approximately 8% Native American ancestry and that his direct matrilineal line is Native American. The program determined that his ancestor Diego de Montoya (born in Texcoco, New Spain, in 1596) was the leader of an encomienda, a protectorate of Puebloan peoples in Pueblo San Pedro in New Mexico. He shares this ancestor with author and commentator Linda Chavez, making them ninth cousins.
