Singer Rita Ora has split from her boyfriend, hip-hop artist Ricky Hil. “The X Factor” judge put the kibosh on their 13-month relationship after matters between them became strained. A source told E News it was a “mutual” decision, but neither Ora nor Hil has commented on it.

Hil is known for his green hair and heavy tattoos. The aspiring rapper, 25, was living with the pop star, 24, when she was in London. He is the son of Tommy Hilfiger, one of the world’s most successful fashion moguls.

Ora and Hil confirmed they were in a romantic relationship in the summer of last year, after meeting at a house party through mutual friends. They spent most of the evening together before swapping numbers. Six months later, the singer and the rapper reportedly were living in her London home.

Ora performed at the Radio City Summer Live 2015 event in Liverpool, England, Saturday. The “I Will Never Let You Down” singer also attended the London auditions for season 12 of “The X Factor” last week.

One source indicated the couple may have had a hard time reconciling their approaches to life. On the one hand, Ora appears ambitious careerwise; on the other hand, Hil seems laid-back. “Their very different outlooks on life seem to have been a factor,” the source said. The couple were spotted together for the last time in June, out and about in London.
