The 26-year-old rapper's mum Myra Anderson has given her seal of approval of his new girlfriend after she watched him and the 21-year-old singer lock lips on stage at her gig in Toronto, Canada.
Speaking to TMZ.com, she said: ''We just saw her last night! She's fun! She's great. Everybody...3,000 people knew he was at the show last night with Ariana, so she's fabulous.''
However, the hunk, 26, was clearly embarrassed by Myra's confession and tried to silence her by saying: ''Hey, hey ... Ariana's amazing ... Mama loves spilling the beans, boy.''
The couple, who have been dating for several months, stunned fans on Sunday (08.03.15) when they shared a passionate kiss onstage at the Air Canada Centre after performing their tracks 'Right There' and 'Best Mistake' together.
However, the show didn't go completely to plan as the brunette beauty was left red-faced when she tripped and fell to knees during her performance of 'Bang Bang.'
But the pop princess didn't let the blunder affect her as she quickly jumped back up and continued to belt out the lyrics to the hit.
Meanwhile, Big Sean - whose real name is Sean Anderson - has admitted his relationship with Ariana is ''pretty serious'' and he hopes to settle down with her and have children.
