Celebrity Big Brother winner Chantelle Houghton last night announced her engagement to fellow housemate Preston.

The couple met during the Channel 4 series in January when Essex model Chantelle was planted as a "fake celebrity" and told to convince the other housemates - including Ordinary Boys singer Preston, who lives in Hove, entertainer Michael Barrymore and politician George Galloway - that she was a singer.

Since then Chantelle and Preston's relationship has been subject of much speculation, but the 22-year-old announced that they were engaged at the New Woman Beauty Awards, at The Dorchester hotel in central London.

She said the ring that Preston had given her was his mother's wedding ring which has "been in the family for quite a while".

"It was as much unexpected for me as it was for him, you know," said Chantelle.

"He asked for his mum to send the ring over, which she done and, you know, he asked me. It just happened."
