Jennifer Lopez and Casper Smart cuddle up on romantic beach vacation

Jennifer Lopez's rumored romance with backing dancer Casper Smart is heating up - the couple has been photographed cuddling on a beach in Hawaii.

The singer/actress is said to have struck up a close relationship with 24-year-old Smart in the weeks following her split from husband Marc Anthony, the father of her twin babies, in July (11).

Lopez has refused to confirm or deny reports about her alleged new beau, saying, "I told everybody... 'Until I'm in a really serious relationship, because of the babies, I'm not really gonna be commenting on my personal life.'"

But the superstar has now been snapped cosying up to Smart for the first time since news of the budding romance broke earlier this month (Nov11).

In the photos, obtained by TMZ.com, Lopez is seen dressed in a skimpy black bikini as she reclines on a luxury beach bed beside Smart, while another shot shows the new couple cuddling.
