The wedding ceremony was held on the Seychelles before a handful of family members and friends, reports The Mail On Sunday.
Van Outen, 35, met her husband when she was judging the BBC One reality TV show Any Dream Will Do, which Mead went on to win.
A source said: "Denise went away last weekend telling people she was simply going on holiday. It was literally just her parents, his parents and a couple of her best pals."
Mead, 27, proposed to the presenter in January before taking her to the Caribbean island of St. Lucia to celebrate.
