Lindsay Lohan

Lindsay Lohan will not be allowed to leave her rehab facility to attend the premiere of her new movie at the Sundance Film Festival.

Media reports claimed the 20-year-old was taking a break from her treatment to attend the famous film festival, only days after checking herself in.

The actress' new film, Chapter 27, also starring rumored ex-boyfriend Jared Leto, is being shown at the festival in Park City, Utah.

Lohan's spokesperson, Leslie Sloane Zelnick, tells E! Online that the star is staying put at the exclusive Wonderland Center in the Hollywood Hills for now.
