Jennifer Lopez is wishing her "coconuts" a happy birthday.

On Saturday  the singer's twins with ex-husband Marc Anthony, Max and Emme, turned 7, and she tweeted out this pic to share their special day.

She says "these two know how to party," referring to the twins, but she and Marc are proving they can have fun together too after their 2011 split.

In October, Lopez sat down with ET's Kevin Frazier and said that maybe one day she'll have more kids, as adoption is not out of the question.

"I might. I don't know. You never know. With me, there's one thing you know: It's that you never know," she said.
