The On The Floor hitmaker worked with RedOne, real name Nadir Khayat, on several tunes on her new album Love? and she says the music mogul brought out her best side.
Lopez, 41, said: 'He is awesome. He's one of the nicest people and has a beautiful spirit. He can just create something the whole world will love and that is probably to do with his international background.
'Some people can do dance, others can do urban or pop, but Nadir does it all and understand what makes a hit on every level.'
Jennifer added to British newspaper the Daily Star: 'I'm a dancer first. That's the conclusion we came to before making any music. I wanted to go back to my dance roots. There's a lot of different flavours on the album. One has a Caribbean feel, another more urban, but RedOne gives you straight-up dance tracks.'
RedOne has worked with Gaga, real name Stefani Germanotta, on several tracks, including her hit Poker Face.
