Ariana Grande is back on the market.

E! News can confirm the 23-year-old singer and her boyfriend, Ricky Alvarez, have called it quits after a year.

A source tells us, "She broke up with him. He didn't cheat or anything, they just found it difficult to make it work. They are still friends though."

The insider also added that she is "happy to be single and do her for a little while."

Grande and the backup dancer were first linked last summer when the infamous video of her licking a doughnut was released to the public. Aside from the doughnut-gate scandal, the surveillance also showed the duo kissing.

A little more than a month later, another insider told us Grande was "happier" than ever. "She and Ricky have gotten pretty close and they are officially a couple," the source said at the time. "They are keeping their relationship on the down low though and trying to be as private as they can."
