Big Sean and Ariana Grande have ended their romance after eight months of dating, the couple have confirmed in a joint statement.

"They both care deeply for each other and remain close friends," reps for the stars said. "We kindly ask that the media respect their wish for privacy regarding this personal matter at this time."

While the reasons for the split are unknown, sources say it was the couple's busy work schedules to blame. "They made the decision to part ways because their conflicting touring schedules would keep them apart over the next year," a source revealed.

Arianana, 21, was first linked to the My Last rapper, 27, in August 2014. Speaking to Telegraph magazine in October, Ariana said the rapper was "one of the most amazing men in the world, and that includes my grandfather and my brother".

The break-up comes just weeks after Justin Bieber was seen grinding with Ariana on stage after he made a surprise appearance at her concert in L.A.

Big Sean wasn't impressed with Justin, venting his frustration on Twitter. He tweeted (and deleted), "This kid is about to learn not to touch my girl like that. Beliebe that."

Big Sean was previously engaged to ''Glee' actress Naya Rivera, who is expecting her first baby with husband Ryan Dorsey.
