Her boyfriend Justin Bieber is famously rather protective of her.

So it’s unlikely the teen idol will respond well to seeing Selena Gomez in a lip-lock with another man.

The 20-year-old Wizards of Waverly Place star however seemed to be making the most of the perks of the job as she puckered up for her latest movie role.

Up close and personal: Selena Gomez puckered up with Nat Wolff on the Sherman Oaks set of Parental Guidance today

Selena was filming scenes for Parental Guidance alongside Nat Wolff in Sherman Oaks, California today.

The kiss they shared was sweet and passionate with 17-year-old Nat tenderly holding Selena’s face as she leaned into him with an arm on his waist.

And even when they weren’t smooching on camera the pair certainly looked like they were getting on like a house of fire.

Perks of the job: While Selena looked like she was having a great time, her boyfriend Justin Bieber probably won’t be pleased

Selena couldn’t stop laughing as she appeared to be picking a feather out of Nat’s hair.

The actress and singer looked adorable in a candy striper’s uniform for the role which showed of her slender legs.

Meanwhile rising star Nat dressed casually in a blue T-shirt and jeans.

Last night Selena and Justin enjoyed a date night and spent the evening at famous Los Angeles comedy spot The Laugh Factory.

Selena’s new film is an adaptation of Ric Browde’s 2000 novel While I’m Dead … Feed the Dog.

Starring alongside Nat and Austin Stowell, Selena will play Nina Pennington in the offbeat coming-of-age comedy.

The story will centre around 16-year-old Ric Thibault (Wolff) and his girlfriend (Gomez) who ends up in the back of a limousine on the road to Rock ‘N’ Roll super-stardom.

The film which was written and will be directed by Tim Garrick, also features Dylan McDermott and English actor Cary Elwes.
