"Party time!!! HAPPY 7th BIRTHDAY TO THE COCONUTS!!" Lopez, 45, captioned an Instagram photo of the foursome. "#thesetwoknowhowtoparty #twins #LOVE #familia."
Anthony, 46, leaned his head on Lopez as the pair smiled big for a selfie with their adorable children. Emme looked like her famous mom's little mini-me. Max, meanwhile, got extra close to the camera and gave a silly face.
Lopez and Anthony split in 2011 after seven years of marriage. They both filed divorce papers asking for joint legal and physical custody of the twins.
The American Idol judge went on to date backup dancer-turned choreographer Casper Smart, whom she split from in June 2014 after two years together. Us Weekly exclusively confirmed in November 2014 that Anthony is engaged to model girlfriend Shannon De Lima.
