When "Samantha Who?" returns tonight at 9:32 p.m. on ABC, Samantha (CHRISTINA APPLEGATE) is forced to move back into the apartment she shared with Todd (BARRY WATSON) when she discovers that she could be evicted for subletting it. But things get more complicated when she discovers that Todd just invited his new girlfriend (KIELE SANCHEZ) to move in with him.

But first, ET went one-on-one with Christina to get the scoop on what direction the show will be taking now that it is back.
