Ariana Grande has joined the Biebs for a few shows on his Believe tour and he apparently swooned not only his fans but her grandmother at Thursday's show!
"Nonna met her love!!! Nonna, Grandpa and @Justinbieber :)," Ariana tweeted, along with a pic of her grandparents and Justin, Thursday evening.
In typical Justin fashion, he responded to the tweet by spitting some game.
"@ArianaGrande post that pic and tell your grandma she is a cutie," Justin replied.
"@ArianaGrande tell grandma I said whatup. Lol. Welcome to the tour," he tweeted too.
"@justinbieber you're crazy and nonna says thank you, she loves you," Ariana posted with a photo of Justin kissing her on the cheek.
Of course, Beliebers started to talk and assumed that the two singers were hooking up.
"Everyone, girls are allowed to be friends with guys. I'm a lady. Chill out," Ariana put on Twitter after people started to say stuff about her and Justin.
Ariana has one more show with Bieber on August 10 in Atlanta, Ga.
