I think she need to go for the hard core p*rn now. The money and her body will not be there in 5 years.
If the footage is all stuff they shot themselves, it is guaranteed to be boring. Were it stuff a network shot of them where they could pick and choose their stuff, you would be pretty sure to get good arguments and other juicy stuff that essentially embarass these celebrities and take them down a notch or two. If Spears controls which bits she gives to UPN, it will be nothing but crap....moreso.
