Kristen Stewart treats her boyfriend, Robert Pattinson, to passionate private dances, a source tells OK!.
Kristen has been practicing the art of striptease since taking lessons for her upcoming film Welcome to the Rileys. (She plays a prostitute/stripper.)
And Twilight co-star Rob reaps the benefits!
"Kristen isn't just good, she's great with the sexy moves," says the source. "She admits to friends she feels super sexy when she gyrates to the music and struts around."
Rob feels pretty good, too.
"Rob already thought Kris was the sexiest woman in the world," notes the source, "but the first time she offered him a lap dance, he couldn't believe his luck."
