He tells MTV, "Britney and I, I did something on her album Femme Fatale, Big Fat Bass, and that experience was such a great experience that we decided to work again and it's been great. I would love to work with Britney again. She has great energy in the studio; she's a sweetheart, a doll of an artist and just a kind, kind person. And when she's in the studio, nothing matters but the music. So that's a great experience to have and share with somebody that loves music."
