Happy hour: Nichola and Caroline had a boozy time at the TV Quick awards

She added: "The press have made comments about my singing abilities and I'd challenge anyone who is making comments like this to come down to the studios and hear me, as I've been singing for years.

"They've also said I only got the record deal with BMG because of Big Brother. Well, however I got it, I would have been stupid to turn it down."

Holt is one of a number of former Big Brother contestants making a stab at stardom now the series is over.

Drunk

Sada Walkington, the first person to be evicted from the house, releases her relationship advice book The Babe's Bible on 9 October - the same day as Holt's single hits the shops.

Andrew Davidson - who boasted of his sexual antics to his fellow housemates - is currently co-hosting Channel 5's Exclusive programme.

But Holt found life in the public eye could be embarrassing as well when she turned up at an awards ceremony with fellow former contestant Caroline O'Shea, and were filmed falling over drunk.

Holt said life since she left the house has been "very intense, very different and very tiring".

"Everybody from the house is doing different things now and we all worked extremely hard to get on the show and I wish them the best luck in the world," she said.
