CAROLINE RHEA LOBBIES FOR GUESTS IN THE LOO

The ladies’ john at a BevHills bash was no “rest” room for Caroline Rhea as she lobbied celeb guests for her debut in the Rosie O’Donnell time slot. Spotting Reese Witherspoon in line for a stall, Caroline introduced herself and babbled: “I’m getting my own talk show . . . I was on ‘Sabrina, the Teenage Witch. . . . You have a toddler, we could talk about kids and. . . ” Reese smiled politely, muttered “Um, yeah,” and escaped into a stall.
