The `Empire State of Mind` singer - who is five months pregnant with the couple`s first child - tied the knot with the music producer on the French island of Corsica. Alicia, 29, wore an ivory silk, Grecian-inspired gown designed by Vera Wang with crystal-encrusted flat sandals, an elegant headband and a bouquet of purple calla lilies. The groom - real name Kaseem Dean - wore a Tom Ford tuxedo with an ivory jacket. Celebrity guests included U2 rocker Bono and Queen Latifah, while the ceremony was conducted by the couple`s close friend Deepak Chopra - who was a close friend of Michael Jackson`s before his death. This is the first marriage for Alicia, while 31-year-old Swizz has been wed before and has two sons. Swizz took to twitter after the ceremony to express his joy. He tweeted: "Wowwwwwwwwww." And later wrote: "It`s a brand new day :) I feel like Nas and Diddy song :) love y`all and blessing! (sic)" Alicia announced her pregnancy and engagement in May, with a friend saying at the time: "She is thrilled. She is with the man who has inspired so much of her music."
