Pop star Rita Ora has reportedly split from her boyfriend Ricky Hilfiger after six months of dating.

The R.I.P. singer is said to have parted ways from designer Tommy Hilfiger's son, who is also known as Ricky Hil, after her hectic schedule caused them to drift apart.

Ora is currently filming the next series of The Voice U.K., where she will act as a judge, and is also busy with her fashion, movie and music commitments.

A source tells Britain's 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. 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."
