Jennifer Lopez Joins Marc Anthony by the Pool in Miami
"It looked like a fun family gathering at the pool," a source tells PEOPLE. "Everyone looked happy and festive."
Anthony, who turned 43 on Friday, and Lopez were at entrepreneur friend Loren Ridinger's guesthouse, which is where the two often stayed before they acquired a condo at Miami's Viceroy Hotel complex.
The night before, Anthony headed to Club 50 at the Viceroy for a birthday bash after his concert at the American Airlines Arena. Lopez, meanwhile, was having dinner at Casa Tua in South Beach.
She is also expected to continue filming Parker, alongside Jason Statham, this week.
Anthony and Lopez were previously spotted together in August in Southhampton, N.Y.
