Kelly Brook and her fiance David McIntosh are in talks to film a wedding reality show.

The 34-year-old model and the former 'Gladiators' star - who got engaged last month, after just 12 weeks of dating - are in early negotiations for a fly-on-the-wall documentary series that would track the preparations for their big day.

A source told The Sun newspaper: ''It's early days but Kelly and David have started talks about some sort of series that will be filmed in the build-up to their wedding.

''They both think it could make a funny, entertaining show and could also pocket them a few quid.''

David is particularly keen to further his TV career and has even spoken to the brunette beauty about possibly making an appearance on 'Big Brother'.

The source added: ''David loves the limelight and will do anything to stay famous.

''He's already been looking into getting on Big Brother and Kelly is right behind him on the idea.''

It is believed Kelly bought her own ring after 27-year-old David, nicknamed Tornado, ''forgot'' to produce one when he popped the question.

Kelly shared a picture of an 'engaged' balloon on her Instagram account to announce the news, taken during a visit to David's family in Wigan, North West England, recently.

She wrote: ''Lovely weekend in Wigan meeting my new extended Family. Such happy times and excited to share my life with the most wonderful man I've ever met.''
