Demi Lovato in sexy blue top: Photo: Actress Selena Gomez will host a prank reality TV show for the Disney network, according to U.S. reports. Gomez, who is currently dating pop prankster Justin Bieber, will test out her comedic chops on an as-yet untitled "alternative series".

A source tells HollywoodLife.com, "Selena shot the pilot and it's basically like Ashton Kutcher's old show Punk'd, but with the Disney kids... Selena was having a ton of fun with it. She's a goof ball at heart."Ironically, Bieber's name has been mentioned in connection to hosting a rumoured revival of Mtv's Punk'd.
