AnnaLynne McCord

AnnaLynne McCord, who already on Tuesday nights plays 90210's naughty Naomi, is going in for another Nip/Tuck (or two) when she resurfaces on the FX drama's next fresh episode, airing Jan. 27.

"I'm reprising my evil vixen role," McCord tells TVGuide.com, referencing her previous run as Eden, an 18-year-old hellraiser who at first merely wanted her virginity "restored," but then went on to torment Sean, corrupt little Annie and poison/shoot Julia.

Where has this bad girl been since wrapping up her original reign of terror? "I've gone off to Europe, but now I come back to... well, I can't say," McCord teases. "But I come back to 'claim something' that's rightfully mine. And then I end up being quite charitable with it."

Um, Eden, charitable...? Says McCord with a wicked laugh, "Yes, it's all very suspicious."

McCord appears on next week's Nip/Tuck, then again on Feb. 24 — and beyond that the door is left open for future encores. That's terrific news for McCord, who calls Eden "by far one of my favorite roles to play. The writing is impeccable."
