Jennifer Lopez and Marc Anthony reunited on Saturday for their kids’ birthday party.

The 45-year-old Boy Next Door actress shared a cheerful snap featuring ex-husband Anthony, 46, and Max and Emme, who both turn 7 on Sunday.

“Party time!!! HAPPY 7th BIRTHDAY TO THE COCONUTS!! #thesetwoknowhowtoparty #twins#LOVE #familia,” she wrote.

Lopez also shared a sweet party photo with her father, David Lopez, showing the pair smiling in front of green and white balloons.

The birthday bash was held at Lopez’s California home and had a Minecraft theme.

Anthony and Lopez announced their split in July 2011, but they have remained on good terms. In her cover story for PEOPLE’s Feb. 2 issue, Lopez opened up about their post-marriage friendship.

“Marc and I have a good rapport,” she said. “We know the kids are the most important thing, and we fill in for each other where the other needs.”

After their split, Lopez went on to date Casper Smart, whom she split with in June 2014 – the same month that her divorce from Anthony was finalized. Anthony, meanwhile, went on to find love again with model Shannon de Lima, whom he married in November 2014.
