Ariana Grande has had her fair share of drama - there was that time she licked a doughnut, then she only wanted to be photographed on one side... oh and her general 'diva-like' behaviour.
This is no exception.
While Ms. Grande is currently (rumoured) to be in a relationship with Mac Miller, someone has called her out for cheating with their man... while they were STILL TOGETHER.
Let's all gasp.
This person is Glee star Naya Rivera.
Naya has given away ALL sorts of juicy gossip in her new book 'Sorry Not Sorry' and she is NOT holding back.
She claims her and boyfriend of one year Big Sean had been fighting for about 5 days straight... she had a key to his house, so she popped on over revealing:
"I walk in, go downstairs, and guess what little girl is sitting cross-legged on the couch listening to music? … It rhymes with ‘Smariana Schmande"
Does that name sound familiar to you?
Ariana and Big Sean started dating after Sean's publicist announced to the world (without Naya's knowledge) they were no longer engaged.
