Rita Ora is reportedly single again after splitting up with her rapper beau.

The Radioactive singer began dating Ricky Hilfiger, son of fashion designer Tommy Hilfiger, six months ago after her relationship with DJ Calvin Harris ended. However it seems that the 24-year-old is back on the market after her hectic schedule seemingly got in the way.

“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,” a source told British newspaper The Mirror. “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.”

Rita will soon be seen on the big screen in the highly anticipated movie adaptation of 50 Shades of Grey. Ricky is also busy working on his own music.

But while the split has come just before Christmas, it doesn’t seem like there are any hard feelings between the two.

“It’s not acrimonious – they just sort of drifted apart,” the insider 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.”

However the source believes the former couple’s paths will still cross, and that sometime in the future if their work schedules allow, the spark could be rekindled.

“They do share a lot of mutual friends, though, so they’re bound to stay in touch,” they said. "However it’s just not practical to be together right now.”
