Jennifer Lopez, Casper Smart relationship 'just about sex'

Jennifer Lopez's relationship with dancer Casper Smart is "just about sex", sources have said.

The 'Papi' singer was recently photographed with the performer and the pair have allegedly been dating for a couple of weeks.

Friends of Smart claimed to The Sun that he has become "inseparable" from Lopez, though both are unsure whether their relationship will be anything more than a fling.

"Casper said J-Lo has an amazing body and she's in better shape than any other girl he's ever been with," a source said.

"He said she's got the body of a 20-year-old. They're inseparable right now. It's just about sex - and no-one's sure if it has much of a future. But he's having a good time finding out."

Another insider revealed that the 42-year-old had an instant attraction to Smart, adding: "Obviously she found his charms hard to resist. With an 18-year age difference, I doubt they have much in common. But who needs conversation when you have that physical chemistry?"

Lopez filed for divorce from husband Marc Anthony back in July. She was previously said to be "casually dating" Bradley Cooper.
