Jennifer Lopez and Marc Anthony reunited to celebrate their children's birthday.

The divorced couple - who has seven-year-old twins Max and Emme together - showed they were on friendly terms as they posed for a photo together.

Alongside the picture, Jennifer wrote: ''Party time!!! HAPPY 7th BIRTHDAY TO THE COCONUTS!! #thesetwoknowhowtoparty #twins #LOVE #familia (sic)''

Meanwhile, the 45-year-old singer and actress recently revealed she has hired a ''manny'' for her son.

She said: ''The poor boy is surrounded by women 24 hours a day. One day I'm looking at him and he like jumps on me and hurts my neck.

''He's so aggressive, he's six and he's killing me. I'm like, 'What the? Baby, no'. And then the nanny is like, 'Ouch, OK Max.' He wants to roughhouse.

''He has this thing and I go, 'This poor kid he's just surrounded by women all day'. I was just thinking of my child and I got a manny, a nice guy to come in and like hang out with him and have fun.''

Jennifer - whose divorce from Marc was finalised in June last year - also wondered how their divorce will affect their children in the future.

She shared previously: ''You didn't hear about divorces so much when you were little and now there's like families and you have to deal with other people's kids and then their partners, and old partners and new partners and it's like such a different world.

''Of course I was thinking about it because I was thinking about my children and how they have to deal with it and how they're gonna deal with all of it, how they're gonna grow up. What's gonna happen when they grow up?''
