Model-turned-producerTyra Banks says she's still undecided whether to re-team with Lindsay Lohan on a previously announced sequel to "Life-Size," the 2000 ABC-TV-movie in which Banks, 40, played a Barbie-type doll come to life. "Right now, we haven't spoken to Lindsay," Banks, who is executive-producing the film, said on the late-night Bravo talk show "Watch What Happens Live." "But you never know!" Lohan's character could "be like, 'Hey, Eve doll, you used to be my Barbie and I'm over you!' She's a woman now!" Lohan, 28, formerly of Merrick and Cold Spring Harbor, will make her stage debut next month in a West End revival of David Mamet's "Speed-the-Plow."
