(Cover) - EN Showbiz - Olivia Wilde insists the Jonas Brothers have put a "no sex hex" on her house.

The Hollywood actress believes her new Los Angeles residence, which was once lived in by the American boy band, is now "haunted" by their spirits.

The 27-year-old beauty revealed that although Nick, Joe and Kevin no longer live in the pad, they left "life size cardboard cutouts" of themselves in the garage.

The brothers are renowned for wearing purity' rings and all vowed to abstain from sex until marriage.

Olivia has joked that their morals are now "haunting" her LA home through the medium of the cutouts.

"Yes, it is comforting," she told Jimmy Kennel in an interview with the TV host. "We blame the Jonas Brothers for the lack of action in our house it's the No sex hex', Jimmy! Can't do anything about it.'"

Olivia doesn't mind having the huge cutouts of the Disney stars in her home. The stunning star says her housemate likes to use them to her advantage at times though.

"Bonus! I didn't even have to pay extra," she joked. "Sometimes I wake up, and my roommate has placed one standing over me."

Olivia split from husband of eight years Tao Ruspoli earlier this year. The gorgeous star has been linked to a number of Hollywood hunks since the split including Justin Timberlake and Bradley Cooper, although she admits she's still unsure about the dating scene.

Olivia can next be seen in Cowboys & Aliens opposite Daniel Craig and Harrison Ford which is released this week. (C) Cover Media
