LONDON: The toyboy lover of Jennifer Lopez claims the 42-year-old has an insatiable appetite for sex, reported British daily The Sun on Tuesday.
Casper Smart, 24, says singer J-Lo has the body of a woman half her age — and is not afraid to use it.
Dancer Casper started working on singer Jen's world tour six months ago, but in recent weeks the pair have been getting to know each other on a series of dates.
They have been spotted partying in Las Vegas and leaving hotels after nights together.
A pal of the dancer said: "Casper said J-Lo has an amazing body and she's in better shape than any other girl he's ever been with.
"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."
A source close to J-Lo confirmed their relationship has developed into "a fun fling", adding: "They're dating and having a good time."
Sources say Casper, of Anaheim, California, is a ladies' man who has dated a string of beautiful women and dances topless in front of screaming female fans at a Hollywood club.
One source said: "J-Lo obviously 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."
Mum-of-two J-Lo split from singer Marc Anthony, 43, four months ago after seven years of marriage. Her previous one-year marriage to dancer Cris Judd, 42, ended in 2002.
