The French star recently released his new double album Nothing but the Beat and he worked with Hudson on a song on the album called Night of Your Life.
Speaking about working with Hudson, he said to MTV News: 'I was in the studio with her. To be honest, I didn't know her so well, but I had heard her voice and I fell in love with it.
'It's a difficult song. You need a really big voice to be able to perform that song. I was like: 'Whoa!' She obviously has an amazing voice, and I think it was a really interesting exercise for her and for me.
'I always love to take singers and take them out of their boxes, and to come with a dance song with her was really exciting.
'She is beautiful in every way: as a person, as a singer, as a human being. She delivered like crazy.'
