Gomez 'not impressed' with Bieber's antics

Selena Gomez isn't impressed with Justin Bieber's "immature behaviour".

The 20-year-old singer's ex-girlfriend doesn't appreciate his recent antics - getting into a fight with the actor Orlando Bloom, posing for flirty pictures with reality star Kylie Jenner and hooking up with Playboy model Alyssa Arce - but friends say she isn't affected by them either, as she is completely over their breakup.
