At the time, there was proof of the infidelity but Kristen hadn't confirmed or denied anything.
Well, now Kristen has released a heartbreaking official statement.
Here's what she said--sadly, the news is true.
"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."
Whoa--is the end of K-Stew and RPattz for good?
Rupert released an apology as well saying that he's "utterly distraught about the pain he caused his family."
Does it make it any better that both of them admitted to their wrongdoings?
