Jennifer Lopez has split from her on-off boyfriend of five years Beau 'Casper' Smart, according to reports. The pair have been dating for five years, though in that time they have already broken up once. Official representatives are yet to confirm or deny the break-up, but anonymous sources insist it's all for real.

The 47-year-old 'Ain't Your Mama' singer first started dating her 29-year-old former back-up dancer in October 2011, but they briefly split in June 2014 before reconciling just a few months later. Now it looks as though it's over for good between J-Lo and her 'Beau'.

TMZ have confirmed the news, via sources from J-Lo's camp, though did mention that sources close to Casper are denying any such thing. People heard the news first though, with their source explaining that it was an amicable break-up and now they're just friends.

'Jennifer and Casper have split. They have not been together for a few weeks', the source told People. 'It wasn't anything dramatic and they were on good terms - it just came to a natural end. They will remain friends and they see each other, but they are not together. It was very amiable.'

It might come as a shock to some that their relationship has come to an end, especially as they appear to have been getting along only recently at Lopez's show in Caesar's Palace, Las Vegas two weeks ago, and at her birthday bash in the city a few weeks before that.

It wasn't long ago that Smart was gushing about his girlfriend to People. 'She's sweet, funny, nice, easygoing and gracious. You can't ask for anything more. She's beautiful', he said, adding that they had a healthy relationship out of the spotlight. 'We don't really go out very much. We both don't drink, we don't do any drugs, smoking, pills or any of the craziness. We don't get wrapped up in the Hollywood life that can chew you up and spit you out. I've seen it happen a million times.'

But it was Lopez who insisted on the 'Today' show earlier this year that she didn't need a man in her life to make her happy. 'Someone can add to your happiness but that's not what's gonna make you happy', she said. 'I had to get happy on my own. It's been a learning curve.'

Representatives for each of them have declined to comment on the media reports.
