Kristen Stewart is admitting to cheating on her boyfriend since 2009, Robert Pattinson and she is publicly apologizing.

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected," Stewart, who was photographed kissing her married "Snow White and the Huntsman" director Rupert Sanders, said in a statement to People. "This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."

On Tuesday night, Us Weekly broke the news about Stewart's cheating scandal, posting the cover of its latest issue featuring a photo of Stewart, 22, kissing Sanders, 41. The photos were taken earlier this month during what the magazine has called a “series of steamy rendezvous in L.A.”

Interestingly, Sanders’ wife, model Liberty Ross, also appeared in the film – as the mother of Stewart’s character. Ross tweeted a photo of herself with Stewart at the premiere. Yesterday, just as news of Stewart and Sanders’ affair broke, Ross tweeted a famous quote from Marilyn Monroe, who knew a little something about cheating scandals, writing, "Sometimes good things fall apart so better things can fall together.” That post was followed by a single word, “Wow,” and then Ross deleted her account soon after.

Sanders has issued an apology as well. "I am utterly distraught about the pain I have caused my family," he said in a statement to People on Wednesday. "My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together."

Pattinson has not yet commented but in an April interview for Italian Vanity Fair he went on record with his feelings about infidelity. "But there's a thing I've never got: That is, why do people cheat?” he asked. “I can understand the impulse. But not how you can keep two relationships going at the same time for long … I'm not the casual-affair kind of guy. If I choose to be with someone, it's because I really want it. When I have a relationship, I'm 100 percent into it."

Hey Rob!  Here's my number...call me maybe!! ;)
