A photo surfaced of Lisa Vanderump that shows the Real Housewives of Beverly Hills star baring her breast.

The image is a still shot taken from the British horror film Killer's Moon and Radar Online posted the photo on its website under the caption "Secret Topless Photo Revealed."

Vanderpump played a character named Anne in the 1978 film, according to IMDb. The storyline revolves around four mental patients who believe they are living in a dream. They leave behind all moral constraints and escape the institution they are in, only to find their way to a nearby busload of stranded schoolgirls.

Most fans now know Vanderpump as a Bravo reality television star and recent contestant on ABC's Dancing with the Stars, but she had an acting career in the 1970s and 80s. Her roles were mostly for television, as she had featured spots in the series' Katy, Leap in the Dark, Sunday Night Thriller and Something in Disguise, to name a few.  She was also on the big screen in 1980's The Wildcats of St. Trinian's.

One of her final acting roles was in 1995's Separate Lives.

Vanderpump had her own Bravo spinoff reality series that recently ended its first season, called Vanderpump Rules. She owns the California restaurants SUR and Villa Blanca with her husband and was eliminated in week 4 of competition of Dancing with the Stars on April 9, where she was partnered with professional dancer Gleb Savchenko.

The day after her elimination she tweeted, "I see how you all feel and I love your support,last night was bittersweet,it was a surreal experience,but today I have my life back."
