Kelly Brook will bare all in front of a live audience for her new US TV show.

The 34-year-old beauty portrays Prudence in 'One Big Happy' and will shoot nude scenes as the ''uninhibited'' ''sexy Mary Poppins'' character tomorrow (04.10.14) and she won't be doing so on a closed set.

A show insider told The Sun newspaper: ''It's a bonus that she's confident and comfortable showing off her body as the character Prudence has no inhibitions.

''The nude scene will be tastefully shot.''

Kelly has already impressed bosses on 'One Big Happy' - which was created by talk show host Ellen Degeneres and also stars 'Love Actually' actress Elisha Cuthbert - with her work so far.

The source added: ''Producers thought Kelly was brilliant and very funny.''

Following her dramatic split for her fiance David McIntosh late last month, the model-turned-actress has been staying positive by sharing snippets of her experience on the social networking site, Twitter.

After posting about their break up, she tweeted: ''Positive changes- Good people -Happy Life- Creative Work. (sic)''

Earlier this week, Kelly also shared: ''Monday Morning Table Read at Warner Bros!!! #Ready #Focused @rebeccacorry Get out of my shot and learn your Lines Sissy (sic)''
