Justin Bieber maybe one of the hottest stars on the planet with millions of women falling at his feet but that didn't stop him getting jealous when Selena Gomez locked lips with her co-star Nat Wolff in their new movie 'Feed The Dog'.
The pair were spotted filming make out scenes last month and it seems Biebs was not at all happy to see his girlfriend in the arms of anther man – even if it was for work.
“Justin is very jealous of Nat,” a source told Star.
“He was furious after hearing Selena tell a friend Nat is a good kisser.”
It seems a surprise appearance on set by the 'Boyfriend' star was the 18 year-old's way of telling Nat to back off.
