Anna Lynne McCord recently told E! Online that she might "lock lips" with the 90210's guest star for this season, Rumer Willis. "This is what I foresee ... Naomi gets drunk, and she gets a little crazy. Liam's watching. Naomi wants to experiment. And then a little lip-on-lip action with Rumer Willis can't hurt anybody, right?"
