It looks like the Butler did it. Last week, whispers began that Gerard Butler had gotten handsy with "Real Housewives of Beverly Hills" blonde Brandi Glanville, who's best known for holding the title of Mrs. Eddie Cibrian before LeAnn Rimes came along. Now, Us Weekly chimes in, claiming their Malibu make-out session on Aug. 27 wasn't a one-time thing. "She's messed around with him on and off since leaving Eddie Cibrian," says a source. "They're friends with benefits. Neither takes the other seriously!"
