Robert Pattinson

Robert Pattinson wasn't a household name... until he starred in Twilight.

Now, the British actor is well on his way to the A-list.

Pattinson appeared in Harry Potter and the Goblet of Fire and Harry Potter and the Order of the Phoenix (in a flashback) in the role of Cedric, but it was his casting as vampire Edward Cullen that truly established the actor in Hollywood. He will star in the next three movies in the Twilight franchise: New Moon, Eclipse and Breaking Dawn.

In his free time, Robert plays the guitar and piano. He has two sisters and was named Rolling Stone Magazine's Hottest Actor of 2008.

At this point, there's no doubt that he's dating co-star Kristen Stewart. To their credit, though, the couple keeps their relationship nice and quiet.

Pattinson was among the 2009 Sexiest Men Alive, as dubbed by People. This a major honor for the star, as he's officially an A-list, mainstream celebrity.
