LEIGHTON TO BLAKE: GIMME A BREAK!

When “Gossip Girl” beauties BLAKE LIVELY and LEIGHTON MEESTER went head-to-head (and boob-to-boob) on the Emmys red carpet, hubbahubba Blake flat-out flattened the competition with a va-va-voom red gown that put the sexy back into awards shows – but totally made Meester see red!

Furious, she stormed up and snarked at stunned Blake: “You got more attention than me because you wore a red dress and I wore white.”

(Note to Leighton: Guys couldn’t keep their eyeballs out of Blake’s plunging neckline long enough to notice!)

Fuming Leighton then dropped this bombshell on dumbfounded Blake: “We’ve got to agree that the next time we’re both booked for a red past carpet event, I’m the one who gets to wear the really bright color. I mean, that’s only fair…okay?”

Instead of knocking Meester on her keister, Blake humored her koo-koo kastmate – and just nodded weakly.
