Jennifer Lopez and Casper Smart are rumored to be planning a "small and simple" wedding so they can work on expanding their family.

The Mirror reports Lopez considers the much younger Smart to be great with her twin seven-year-olds and is really keen on the two having a child of their own.

"They've already started trying," said a source. "And he'd love to be able to reveal on their wedding day that they're expecting."

Rumors are the nuptials would take place at Lopez's Hamptons home, with guests being told it is a party rather than a wedding, just as Jennifer Aniston and Justin Theroux recently did with their guests at their Bel-Air home.

The 46-year-old Lopez has already been married three times before: to Ojani Noa from 1997 to 1998, Cris Judd from 2001 to 2003, and Marc Anthony, the father of her twins, from 2004 to 2014. Lopez has also dated such heavyweight celebs as Ben Affleck, Sean Combs and Wesley Snipes.

A choreographer by trade and once one of Lopez's backup dancers, Smart recently beamed Lopez "crushes on" every routine he gives her.

When recently asked if she was his favorite client, Smart responded, "I have a top four. Nicki [Minaj] and I just click really well and I love her music. Nick Jonas is so young but extremely focused and great to work with. Jennifer crushes everything that you give her. Jessie J is like a comedian. She's hilarious."

Just this weekend, Lopez and Smart were spied on a romantic dinner date in West Hollywood, where they appeared to be trying to keep a low profile. The two split last June, but all this summer have looked like quite the couple.

At Lopez's birthday bash in the Hamptons late last month, the two were spotted holding hands.
