The 46-year-old is allegedly planning to marry her toyboy lover Casper Smart – and she's going to do a 'Jennifer Aniston' and say 'I Do' in secret.
A source told OK! Magazine: "She doesn't want everyone else weighing in on whether getting married again is the right thing to do.
"Casper's great with the twins and he really wants to have a baby of his own too.
"They've already started trying, and he'd love to be able to reveal on their wedding day that they're expecting."
And, just like Jen An, J.Lo and Casper, 28, are allegedly considering her home in the Hamptons as an ideal location for their big day.
Jennifer and her third husband Marc Anthony divorced in June last year. They share seven-year-old twins Max and Emme.
Before that, Jenny From The Block was married to dancer Cris Judd from September 2001 to June 2002, and waiter Ojani Noa from February 1997 to January 1998.
After two years of dating, Jennifer and Casper split in June 2014 but reunited in May this year.
Speaking last year, Casper revealed he and Marc get on well. He said: "We're buddies. Anything can be awkward if you let it be awkward. When kids are involved with anything, you can't let ego, pride or any of that get in the way because they're most important."
Could it be fourth time lucky for Jennifer?
