As Big Brother winner Chantelle Houghton enjoys being Britain's number one celebrity, her brother Gregg is quietly getting on with his job at Towergate Underwriting.

Insiders say talent runs in the family - the professional indemnity account handler is a star performer at the Leadenhall Street offices.

Gregg still lives at home with his famous sister and their parents at Wickford, Essex.

He says he has no plans to cash in on his sister's fame, which he admits has still not hit home.

When asked if he's now under pressure to achieve, he said: "I'd better get on with being the next Peter Cullum then."
