Lauren Conrad's ex boyfriend Stephen Colletti is dating Chelsea Kane, the Dancing with the Stars cutie, 22, tells Us Weekly.

"We were set up on a blind date by my manager," she says.

It turns out the dancer has been a fan of the 25-year-old One Tree Hill actor since his days with LC on MTV's Laguna Beach.

A source close to the dancer tells Us, "She tore his photo out of a magazine to show friends!"
