Did you hear the latest on Queen B?

Word is she’s ditching the Upper East Side for the West side…for at least one episode, anyway.

Sources confirm that the fabulous Leighton Meester is heading back to L.A. shortly to shoot scenes for HBO’s Entourage! We’ve been told she’s set to pop in somewhere in the first half of the upcoming season for at least one episode.

Leighton will be reprising her season-one role of Justine Chapin, a then-virginal pop singer based on Britney Spears. She had a mad crush on Vinnie back in the day, and something tells me she might stand a better chance now that she’s all growed up and hot as fire.

No word back yet from HBO, but we’ll let you know if/when we get it.

(Interesting note: Leighton has the same manager as Mark Wahlberg.)

So, are you looking forward to Queen “B” on “E”? And do you think she’s a better match for Vinnie or Chuck? Weigh in below…
