SPOTTEDLeighton Meester shacking up with Robert Pattinson.  No wonder the Gossip Girl star broke up with Sebastian Stan last week.


According to Perez Hilton, sources have reported sightings of Pattinson entering Meester's NYC apartment SEVERAL TIMES in the past week... and not leaving until the next morning!

A source also said:

"He ducked out of the building and hopped into a waiting car. He apparently spent the night with Leighton, and didn’t want anyone to know!  She’s having a texting romance with him, and is so into it. She talks with Rob almost daily.”

Edward Cullen and Blair Waldorf!  Should we start picking out a nickname for the duo?

What do you guys think!?  And  more-so... what do you think Kristen Stewart thinks??
