Ariana Grande and Big Sean Relationship News Update 2015: Is Couple Still Together After Reported Cheating Accusations Following Suspicious Texts?

Big Sean reportedly did not cheat on girlfriend Ariana Grande after all, but why was he texting other women?

Star recently reported that Grande found a bunch of texts and photos from other women on the G.O.O.D. Music artist's device.

"He tried to play it off and swears he hasn't hooked up with anyone since they became official, but Ariana was devastated," a source said. "She couldn't believe the sort of things she saw them talking about to him."

The source added the "Break Free" singer immediately dumped the "IDFWU" rapper.

"She refuses to return his calls," the source explained. "She feels completely violated and has lost all trust in him. His grandma passed away a few days later, and she hasn't even called to check up on him. They're done!"

Reps for Grande insisted that the claims were "absolutely not true," Daily Mail reports, and the couple also cleared up the split rumors by sharing several PDA photos on Instagram.

However, it is true that the Detroit emcee was talking to other women; when he lost his grandmother, other females, including some of his exes, reached out to give him support.

"Ariana thought Big Sean was seeing other females because after his grandmother died, a lot of his exes and female friends called him and were telling him that if he needed anything, they were there for him," a source told HollywoodLife.com. "His phone was blowing up with phone calls and texts, and he was with Ariana some of the time. She saw girl after girl blowing him up and like most women, her mind automatically assumed he was cheating, but she shouldn't have thought that. Big Sean had to explain to her that those females were just trying to be supportive. Still, even now, some women from his past are checking up on him to make sure he's alright, but he's assuring Ariana that nothing more is going on.
