Jennifer Lopez and Alex Rodriguez have a "nice dynamic"

Speaking to 'Extra', she said: "When you have a partner that is so supportive of what you do, you don't have to hold back.

"With him, it's like, how much more do you want to do? How much bigger do you want to get? How can I help you? Where do you need me to be?

"And I like to do the same for him. It's just a nice dynamic that I have never experienced, and I am really happy about that."

Jennifer recently revealed just how much she appreciates his approach towards her career, admitting her jam-packed schedule can be a "grind".

She previously explained: "To have a partner who's that supportive, who comes to that many shows - we all know what it's like to be in show business. It's a grind.

"It's being away a lot and he really makes the effort, so do I, to be there for each other and it means a lot to me."

Alex - who has Natasha, 13, and Ella, 10, with his former wife Cynthia Scurtis - recently admitted he thinks his relationship with the 'World of Dance' judge works so well because they've shared similar experiences throughout their lives.

He said: "We're in our forties. We're both from New York. We both come from Latino backgrounds. We both have two kids. I think we've both been through a lot and can really appreciate each other - both the good and the challenges."

His commets comments echo similar ones made by Jennifer - who has 10-year-old twins Max and Emme with her former husband Marc Anthony - when she said timing was everything.

She said: "We were both at a good place in our lives. And I think, maybe if we had met in our twenties, it wouldn't ... you know, maybe not so much. We're too crazy. But now, at this point in our lives, where we both have kids and we both accomplished certain things in our careers and we're kind of in that second act of our lives, we really complement each other."
