Breaking Dawn? Or is it more like, "breaking up"?

Kristen Stewart and Robert Pattinson sadly got into a huge fight on his birthday this week, and it's a result of Kristen feeling underappreciated, according to Hollywood Life.

"Rob is not treating Kristen like a princess and she’s getting fed up with it," a source says.

"He’s not as into it as he was before the cheating — not giving her special treatment like he used to," the source continues. 

It has seeming lately that the Twilight twosome had been getting along famously, as they were spotted together on low-key dates and bought each other lavish gifts.

But they reportedly fought on Rob's birthday on May 13, with Kristen reportedly talking to him on the phone for almost an hour at a friend's house, rather than hanging out with him in person on his special day. 

"She feels unloved and that’s why they fought," the source says.

So does this mean they're dunzo?

"They’re not split, but they’re holding on by a string," the insider clarifies. Yikes.

We were really hoping that the two had put their issues behind them, so this is very disappointing news. 

C'mon, you two  we're rooting for ya!
