Demi Moore is how old again??

48 year old Demi Moore is looking hotter than ever these days. She was spotted on the beach with her much younger hubby Ashton Kutcher.

Upon first glass it just looks like Ashton is just reading a regular book right? Well let's zoom in a little more...

He's reading a book called the Youth Pill. The book apparently gives tips on how to stay young. I get the feeling we may all be getting punk'd. Why on earth would be need a book about staying young? His wife is clearly drinking from the fountain of youth. C'mon Ashton, this must have been a joke for the paps!
