Selena Gomez is a vision of beauty in the trailer for her latest movie Behaving Badly - literally.

The 21-year-old pop star is seen blowing a kiss to Nat Wolff as his character enjoys a romantic daydream during a lesson at school.

Sel-Go plays Nina Pennington in the teen comedy, with Wolff playing a high school student named Rick Stevens who is attempting to win her heart.

However the trailer reveals that he has to contend with a possessive ex-BF, a pair of cougars and his sister turning their home into a lap-dance club along the way.

The movie is out on 1 August in the US - with no UK release date yet revealed.

There have been rumours of a feud between Selena and Demi Lovato after Demi unfollowed her celeb pal on social media.
