Jennifer Lopez is embracing her modern family, posing for a photo sandwiched between ex-hubby Marc Anthony and her current boytoy Casper Smart, and RadarOnline.com has the details on why the exes reunited.
"Happy Birthday Cristian!!!!!!!!!!!!!!!!!!" J.Lo tweeted along with the photo on Thursday night.
Marc and Jennifer split in July 2011, and officially filed for divorce last April but the two remain on amicable terms — with a recent report even stating the two had a secret rendezvous last month while in New York City.
"Happy birthday to my prince Cristian!" Marc also tweeted on Thursday with the photo, and even tagged J.Lo, Casper and Shannon.
Also in the photo is Marc and Jennifer's 4-year-old twins, Max and Emme.
