Jennifer Lopez's beau Casper Smart apparently feels ready to become a father.

The backing dancer has been dating the American Idol judge for a few months and has bonded with her four-year-old twins Max and Emme, from her marriage to Marc Anthony.

Star magazine claims that although the 25-year-old was hesitant at first about having children, he is now on board to add to Jennifer's brood.

'Jennifer has always dreamed of having three or four kids,' an insider told the publication.

'She knows that if she is going to be a biological mom again, it has to happen sooner rather than later. So she's decided to just let nature take its course.

'Jennifer and Casper spend all their spare time together ' and he is crazy about the twins... Casper has now had a change of heart after seeing what an amazing mom J.Lo is to the twins.'

However, other sources close to 42-year-old Jennifer insists she is in no rush to have another baby.

The star reportedly wants to make sure she is settled with Casper before she thinks about getting pregnant.

'[She would like another child] but that would only be after Jennifer is 100 percent sure their relationship is on solid ground and is going to last,' a source told Chicago-Sun Times.
