While we would love nothing more for this to be true, it sounds a tad off to us?
Stewart in a black dress rocking out to Jay-Z and swapping spit with her boyfriend in public certainly doesn't sound like the robsten we know.
So what do sources at the same party tell us?
That they didn't see them there, either.
Maybe they were just extra sneaky? Or maybe they just weren't there at all.
But don't fear, because we do have a fab sighting of the two of them from the weekend!
Rob and Kristen were spotted at American Vintage in Sherman Oaks on Saturday and, apparently, the cuteness was out of control.
"It was very obvious they were so in love," an employee told us. "Rob was a total gentleman, and was very attentive to Kristen. He also paid for everything they bought."
One thing R.Pattz bought his lady?
The American Vintage employee dishes he got Kristen a leather jacket. In fact, it's the same one she was seen wearing at LAX Sunday.
Say it with us now: awwww.
We're also hearing, though not 100 percent confirmed, that Robsten was spotted at a vet in Ventura Friday afternoon and the Griffith Observatory late Friday night—which would also make the Us Weekly story hard to believe.
Glad they had such a cute weekend, but it's back to work on Breaking Dawn now.
Oh, and for what it's worth, we contacted Summit to see if those rumors about casting two Renesmee's (one would be a teenager) is true.
"Summit is not commenting—can neither confirming nor denying."
That sounds like a yes to us!
