Though they separated back in July 2011, Jennifer Lopez and Marc Anthony can still put aside their past for the sake of their children.

Recently, the former couple reunited to celebrate Marc's son Cristian's 12th birthday. A photo that J-Lo posted on Twitter on Thursday (February 7) captures the whole family posing with the birthday boy, including her boyfriend Casper Smart and Marc's girlfriend Shannon de Lima.

Though the former "American Idol" judge is not biologically related to him (the boy is from Marc's relationship with ex-wife Dayanara Torress), Ms. Lopez was genuinely thrilled to celebrate the milestone. With the happy photo, she tweeted, "Happy Birthday Cristian! House party. Familia."

Also in the photo were the former Latino power couple's four-year-old twins from their marriage, Max and Emme.
