Jennifer Lopez & Marc Anthony Reunite for His Birthday

Jennifer Lopez helps estranged husband Marc Anthony celebrate his 43rd birthday at a mansion on Saturday (September 17) in Miami, Fla.

The two, who split in July, hung out in the backyard with their 3-year-old twins Max and Emme.

The night before, Jen dined at Casa Tua, while Marc performed at Miami’s American Airlines Arena.

During his sold-out concert, the crowd sang “Happy Birthday” to him, prompting a teary-eyed Marc to fall to his knees.

Marc thanked the audience for “all your love and support, especially this year; it means a lot to me,” he said, according to People.
