Rita Ora and her boyfriend of six months Ricky Hil have called time on their relationship.
The singer and rapper - both 24 - have gone their separate ways after dating for half a year, because they "drifted apart" due to her busy schedule.
A source told the Daily Mirror newspaper: "Rita is so busy she is just flat out at the moment.
"She's recording 'The Voice' on BBC1, she has campaigns for make-up, clothing and a perfume coming out.
"Not to mention featuring in a Hollywood film, performing for the Obamas this week and recording her second album.
"Realistically, she doesn't have time for a steady relationship. It's not acrimonious - they just sort of drifted apart."
She has however vowed to stay friends with Ricky, but realises it isn't "practical" for them to continue their relationship.
The source continued: "They had a great time in Marrakech last month for her birthday but since then she has been working non-stop in the States.
"As much as she liked Ricky, her career is her priority at the moment, while he's working on his own album.
"They do share a lot of mutual friends, though, so they're bound to stay in touch.
"However it's just not practical to be together right now."
This split comes as Rita's second of the year after she separated from DJ Calvin Harris after over a year of being together in June.
That break-up was also blamed by Rita on her schedule, with her recently saying: "There's only so much you can do when you don't see each other. I really admire people who have long-distance relationships. It's an incredible achievement. I couldn't do it.
"It was the right guy at the wrong time. I was about to start a tour, and he was also all over the place."
