Leighton Meester & Robert Pattinson Dating?

Leighton Meester recently had a rendezvous with Twilight star Robert Pattinson at her New York City apartment, according to reports.

Did it ever happen?

“Not true,” a source exclusively tells JustJared.com. “How could Leighton and Robert have been hooking up if they’ve never even met? Impossible.”

So relax, Twi-hards! Robert was in Hungary celebrating Kristen Stewart’s birthday over the weekend. He’s probably not even in the country!

Leighton Meester splits with Sebastian Stan?

Two real-life Gossip Girl couples may have bitten the dust.

Leighton Meester, aka Blair Waldorf, and Sebastian Stan reportedly called it quits. OK! is saying Leighton pulled the plug because she “doesn’t really like” relationships.

Ed Westwick, aka Chuck Bass, and Jessica Szohr also reportedly broke up recently. NY Post is saying he ended the relationship with her over the phone.

If these break-up reports are true, things sure will be awkward on set next season!

On a happier note, it’s Leighton’s 24th birthday today. HAPPY BIRTHDAY, LEIGHT!
