(USA TODAY) -- Yes, Rihanna and Chris Brown are supposedly over and done with. Again.
E! quotes an unnamed source as saying RiRi will always love Chris but has moved on and is shifting her focus to her career and business ventures.
At Monday night's Staples Center concert, Rihanna rocked the house, with moves that included sticking out her tongue and highlighting her crotch with both hands.
Early Monday, reports TMZ, the star stopped into Greystone Manor nightclub in Hollywood, where she was spotted smoking a joint.
Meanwhile, Chris Brown was snapped holding the hand of Keisha Kimball, 22, a waitress at L.A.'s Playhouse nightclub on Saturday. But she tells TMZ not to blame her for the breakup. "I know him and am friends with his friends. Nothing has ever happened. I just work there. In the photos, he was handing me a bottle to drink out of. Of course people are going to twist it another way."
