Selena Gomez dumps Justin Bieber over Kylie Jenner

Selena Gomez has dumped Justin Bieber over his friendship with Kylie Jenner.

The Come and Get It hitmaker - who was seen cuddling up to her on/off boyfriend at the Coachella Valley Music and Arts festival earlier this month - is said to have been annoyed by Bieber’s closeness to the reality TV star, despite them hanging out as a group, along with Jenner's sister Kendall, at the Californian event.

A source said: "Selena is convinced something has gone on between Justin and Kylie.

"At Coachella they looked to be back on track. Selena was hanging out with Kylie too and they were behaving like best friends.

"Then she heard stuff about Justin and Kylie and felt totally betrayed. She went berserk and called it all off again."

The 21-year-old star is said to be "overcome" with jealousy and has unfollowed the Jenner sisters on Instagram and deleted all her pictures with the pair.

However, friends think she is channelling her emotions in the wrong place and want her to focus on cutting Justin out of her life.

The source added to The Sun newspaper: "Selena is in a really bad place at the moment -- she's on the edge and now overcome with jealousy.

"She really needs to wash her hands of Justin for good."
