Actress-model Kelly Brook will bare it all in front of a live television audience for her new show "One Big Happy".

According to a report in The Sun newspaper, the 34-year-old, who plays Prudence in the series, will shoot naked scenes as the "uninhibited sexy Mary Poppins" type character Oct 4, reports femalefirst.co.uk.

"It's a bonus that she's confident and comfortable showing off her body as the character Prudence has no inhibitions," said a source.

"The nude scene will be tastefully shot," the source added.

Brook's work so far has already impressed producers, who apparently think the star is "brilliant and very funny".
