Celebrity Week In Review: Kristen Stewart Cheats, Rihanna Flies High

It's been quite a dramatic week in Hollywood.

Photos of Kristen Stewart cheating on boyfriend Robert Pattinson hit the Internet Tuesday night and, needless to say, "Twilight" fans went crazy. Even more shocking than the photos? Stewart's heartfelt apology to Pattinson, in which she proclaimed to the world, "I love him, I love him, I'm so sorry."

Yikes, it must be really bad if Stewart is willing to speak so candidly about her private life.

(BTW, how happy must Tom Cruise and Katie Holmes be to have the spotlight taken off their split?)

Of course, other things happened this week besides all of the Robsten drama, so check out some other news and photos below:
