The "Problem" singer, 21, and the Detroit rapper, 27, announced their parting of ways in a joint statement issued to the Los Angeles Times on Monday.
"They both deeply care for each other and remain close friends," the statement said. "We kindly ask that the media respect their wish for privacy regarding this personal matter at this time."
Us Weekly reported that the breakup was "quiet" and the relationship ended amicably a few weeks ago. Insiders quoted by the magazine, which was first with the news, chalked up the split to "conflicting touring schedules" that would separate them for the next year.
The petite powerhouse and the "Blessings" emcee, who collaborated on "Big Mistake," took their time in confirming their relationship despite being spotted together on numerous occasions and making cameos on one another's social media accounts.
There didn't seem to be any indication of trouble in paradise just last month -- that's when the Nickelodeon alum brought her beau out onstage for a duet and plenty of PDA during her Honeymoon tour's stop in his hometown.
