Justin Gaston Models Christian Audigier

Miley Cyrus licks her lips as she cheers on model beau Justin Gaston walking the runway at Christian Audigier‘s American Lord fashion show on Wednesday in Culver City, Calif.

Joining Miley during Mercedes-Benz Fashion Week at Smashbox Studios was momager Tish and big sis Brandi, both of whom hollered for their boy Justin.

When 20-year-old Justin was asked by E! if he’s dating 15-year-old Miley, he said, “We’re friends. We’re good friends [though] you never know what’s going to happen. I take it one day at a time.” Watch the video below!
