One of today’s biggest Hollywood heartthrobs is Adrien Grenier, most known for his breakout role as Vincent Chase on HBO hit Entourage. Prior to his big role, he had the leading role in the film Drive Me Crazy opposite Melissa Joan Hart. His success on Entourage led to a role in the mega-hit The Devil Wears Prada opposite Anne Hathaway. One of Hollywood’s most eligible bachelors, Adrien surprisingly hasn’t been linked with any one starlet for too long.
