Tom Cruise and Katie Holmes' favorite song is Kanye West's hit "Gold Digger."
Music producer Mark Ronson acted as DJ at their wedding and said the newlyweds went crazy on the dance floor when he played the track.
Mark revealed to Britain's Star magazine: "It was actually a really sweet wedding. I know there's a cynical attitude towards it and I wanted to got here thinking that, too, but as soon as I saw them together, they are genuinely in love.
"Who knows what happened after that, but that night they seemed very happy. They both went crazy when Kanye's 'Gold Digger' came on."
The couple married last November in front of more than 150 star-studded guests at Italy's Odescalchi Castle, in Lake Bracciano. Guests included Jennifer Lopez and her husband Marc Anthony, Jada Pinkett Smith and her actor spouse Will, Jim Carrey and his girlfriend Jenny McCarthy, former Spice Girl Victoria Beckham and Brooke Shields.
Katie wore an off-the-shoulder Armani wedding gown with an ivory silk train complete with Swarovski crystals, while Tom said "I do" in a navy blue tuxedo also designed by Giorgio Armani.
