Kristen Stewart admits to cheating on Robert Pattinson, our jaws drop

Kristen Stewart and Robert Pattinson seemed like one of the most solid couples in showbiz. The fact that they kept their relationship so private, yet seemed so loved up any time they were pictured together pretty much gave us relationship envy each time we laid eyes on them.

Kristen says: "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."

Rupert quickly hit back with a statement of his own, saying: "I am utterly distraught about the pain I have caused my family. 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."

However, just yesterday Liberty Ross tweeted the quote: "sometimes bad things fall apart so better things can fall together," before deleting her Twitter account.

So far, Robert Pattinson is yet to comment on the news. We're seriously reeling.
