I guess having a bad boy just wasn't enough, because Ariana Grande and Nathan Sykes have reportedly called it quits.

Just a few months after releasing their "Almost Is Never Enough," track, the former couple confirmed their relationship on Twitter in September and have been traveling together ever since.

According to Mstarz, "In her Teen Vogue cover story for the February 2014 issue, Grande opened up about her relationship with Sykes, telling the magazine:

"It's not as tough as people would think," the singer said. "We have the same music manager, so we can see each other's schedules and plan little trips as often as we can."

But what happened? The two seemed to be really into each other and constantly sang praises of the other. Even their relationship announcement was pretty cute.

"So, I guess it's obvious now," Sykes tweeted back in September. "Thanks to everyone who is being so lovely. I'm so happy #but weareterrified #pleasedontkillme #orariana"

Another insider also shared the possible reason for their split, saying; "They just weren't into it anymore," the source said.
