Why did Ariana Grande really break up with her boyfriend? Image: AAP Tue-05-Aug-14 19:51 Share this By Steph Monks Ariana Grande has broken up with her Janoskians boyfriend Jai Brooks. They only got back together a couple of months ago, but they’re done-zo this time apparently because he wasn’t there for Ariana when her grandfather passed away last month. She felt like he wasn’t there when he should have been. She posted this message on Twitter:love u pic.twitter.com/Xfa5bTT4vL— Ariana Grande (@ArianaGrande) August 4, 2014 You May Also Like Guy, Sharyn and Clint chat to Ariana Grande Music video for Bang Bang will make you WANT a summer party The Janoskians are coming to NZ Become a fan of The Edge on Facebook and on Twitter .
