Selena Gomez and Justin Bieber Extreme PDA on Set of 'Feed the Dogs'

Former Disney princess, Selena Gomez may have called it quits with Disney but that didn't mark the end of her career. In fact, Selena's career had gone up for the past few months. With two albums set for release this year and three films wrapped up, Gomez still has enough time to make more films plus get all PDA with Bieber on the set of her current film, "Feed the Dogs."

Gomez may have wrapped up production on "Spring Breakers", "Hotel Transylvania" and "The Getaway" but that didn't wrap up her film projects for the year. In fact, Gomez is back on set for yet another film, "While I'm Dead... Feed the Dogs." The film is based on the novel written by Ric Browde which tells the story of a 16-year old boy, Ric Thibault.

The plot is as stated: "While trying to get into the pants of the most beautiful girl in the world, sixteen-year-old Ric Thibault ends up in the back of a limo on the road to rock'n'roll superstardom opening up for Bowie. But on the way there he hits a bump or two - a few dead Mafia hitmen here, a nymphomaniac next door there, not to mention a few dying Latin teachers, narcoleptic nuns, inept policemen, unscrupulous lawyers, buffoon reporters, huckster televangelists and greedy relatives."

Being on film sets half of the time, it's no surprise that Justin Bieber had made a surprise visit on his lady love. Canadian crooner, Bieber despite the busy schedule of world tours made a visit on set of "Feed the Dogs." The lovebirds immediately went into PDA mode prompting paparazzi to take multiple photos of the duo locked in sweet embraces and smooches.

"[Justin and Selena] couldn't keep their hands off each other as they walked around base camp near the set," says a source to Gossip Center.

While some "Jelena" fans may pass it off as a sweet visit from Bieber, some tabloids have been claiming it a way for Justin to keep his eye on Selena. Gomez having been paired off with the hunky, Nat Wolff, had stirred the green-eyed monster in Justin.

Well, whatever the tabloids say, Selena Gomez doesn't strike fans as the cheating type unlike some celebrities putting up a "clean and pure" vibe.
