Sarah Harding has announced she has split from her boyfriend.

The 33-year-old Girls Aloud star – who recently joined the cast of Coronation Street – had been dating a mystery man known only as Jason for around six months.

Sarah posted a link to an interview with The Sun in which she talked about Jason on Twitter and added that she is now single.

Sarah had told the newspaper: “He’s at completely the opposite end of the spectrum compared to the other guys.

“What I mean is he’s definitely more stable, much more career-focused – the pair of us are, which means we don’t see much of each other at the moment, which is quite sad. But we’re both really hard-working people and we just want the best for our futures.

“Some people say it’s nice to be with someone who is involved in the industry because they understand your job and blah, blah, blah. But, you know, the last few boyfriends I’ve had have been in the music business and they’ve not gone so spiffingly.”

The singer entered rehab shortly after the end of her four-year relationship with DJ fiance Tom Crane in 2011 and last year split from music producer Mark Foster after almost two years together.

The singer had said at the end of last year that she wanted to be single for a while and explained: “I just needed a break from men. I needed time to find my true self and not to feel like I was relying on a man. I don’t want to feel like I need to have a boyfriend.

“You have to love yourself before you can love someone else and I was always very insecure. After the breakdown of my last relationship with Mark (Foster), I needed time out to stand on my own two feet and become a strong woman.”

In March this year she spoke of her hopes of getting married and having children.

She said: “Of course I’d love to get married. I’m hoping it will happen in my 30s – marriage and kids would be good in my 30s. Two or three children would be nice – I’ll knock a few out!”
