To be honest,most famous "celebrities" now a days do absolutely nothing for me and a lot of the ones mentioned here by other posters,I have never heard of(yeah, I know...
)
But,there is at least one celebrity that I am guessing is close to my age that I wouldn't mind "do"ing
Candice Night(aka Mrs Ritchie Blackmore)
She sings and has that whole Renaisance Fair maiden thing going on.Don't how good of a cook she is,but with a face and body like that,who cares?
