kstewart060312_04_X17crop23.jpg Hot on the heels of an US Weekly cover story that exposed her affair with Snow White and the Huntsman director Rupert Sanders, Kristen Stewart is coming clean about her indiscretions in a public apology to boyfriend Rob Pattinson.

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. 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," the actress said in a statement Wednesday.

Pattinson, 26, and Stewart, 22, were together as recently as Sunday, when they attended the Teen Choice Awards together and appeared to be all smiles. Still no word from the scorned Twilight actor or his reps.
