On Saturday, the day after he turned 43, Marc Anthony got a very special birthday visit at his Miami home: from Jennifer Lopez, his ex-wife-to-be.

Both Anthony and Lopez, 42, was photographed hanging by the pool with their 3-year-old twins Emme and Max at the sprawling Florida home they once shared. The couple announced the end of their seven-year marriage back in July. See more pictures from Marc's birthday.

Lopez, on a break from filming What to Expect When You're Expecting, kept it casual in a blousey white top, shorts, wedges and oversized sunglasses.

The night before, after performing an emotional, sold-out show, the newly-single Anthony partied with about 150 pals at Club 50 (at Miami's Viceroy hotel) -- sipping champagne and beer and chowing down on a birthday cake made by Ace of Cake's Geof Manthorne.

At the bash, Anthony told Us Weekly about his fave b-day present: "Being with my family yesterday, spending time with my kids."

He added that his kids Emme and Max are "beautiful."

Are he and Lopez still good friends? "Absolutely," the Latin crooner told Us.
