Actress Mischa Barton has made a guest appearance playing herself in Willis Earl Beal's new promo.

The former O.C. actress plays a member of a cult-like group led by Beal in the 10-minute video for his track Coming Through.

She stars as a naive newcomer who gets brainwashed by Beal, who is wearing a balaclava and ski mask throughout the clip.

The video is made up of grainy camcorder footage and soon descends into the bizarre when Beal takes the group to a desert and urges them to simulate sex on the ground.
