A spokesman for Chantelle Houghton has said that she and ex-husband Samuel Preston have "unfinished business".

The couple married after their stint together on Celebrity Big Brother 4 and their recent reunion on Ultimate Big Brother sparked rumours of a reunion.

Houghton's spokesman Mark Thomas told the Daily Mail: "They haven't had a love-in. Well, not yet, no. But they do want to have some time together. They're definitely talking to each other and coming to terms with their feelings.

"It's too early to say there's a romance yet, but they've got unfinished business, let's put it that way."

Of reports that Houghton is planning a breast reduction to please Preston, Thomas added: "She hasn't decided what to do about her boobs yet either."

Thomas confirmed that the former couple have teamed up for a photoshoot with OK magazine, the publication which covered their 2006 wedding for £300,000.
