Our hearts have been crushed, our souls ripped apart, and our very reason for living called into question - but that's nothing compared to how scorned Robert Pattinson must be feeling right now.
Brace yourselves for the emotional onslaught coming your way.
A showbiz insider (aka nosy gossip) saw Rob and Kristen chatting backstage at the Teen Choice Awards on Sunday night, around the time Rob's reported to have found out about the news.
"Rob and Kristen were having a long and intense conversation backstage, and he looked miserable, heartbroken and humiliated," they told the New York Post.
"She was pleading."
"Rob is deeply in love with Kristen and is very jealous when other men hit on her," added another gobby gabber.
"This will crush him."
Kristen has issued an apology for her secret shagging, saying she's "so deeply sorry" and revealing she's in love with Rob.
