Queen B 'BUKAN SEPERTI YANG KORANG TENGOK KAT TV'

We know Leighton Meester plays a sometimes snotty brat on Gossip Girl, but did life imitate art Tuesday night?

Earlier that evening, Leighton was all smiles with her fellow castmates while attending a book party for their wardrobe stylist, Eric Daman.

But later, things got ugly when some of the crew, including Leighton and Ed Westwick, headed to Philippe restaurant.

According to the New York Post, their group was "cursing and talking so loudly that other customers complained." One patron reportedly asked her to keep it down.

Meester's alleged response?

"F--k you! How dare you tell us to keep it down?" the Post claims was her reply to the reasonable request.

Philippe had no comment on the alleged incident, but a source confirms the story to E! and says, "There was cursing and yelling."

Luckily, Westwick came to rescue, smoothing things over and hugging it out with the peeved patrons. Just one more reason to love Chuck Bass.

As for , we like you bitchy on TV, but not in real life, 'kay?

Reps for Meester and Westwick did not respond to request for comment.
