There's the problem. She doesn't know she has turned into a regular person.
Her point of reference is all fucked up. As a celebrity, she's a disaster. As an average person, she's got a lot going for her.
Just pick a decent guy with a job, and live life. No problem.
There's a lot of truly hot older chicks.. Look at Sandra Bullock at 43. I don't know anyone who'd pass that up.
Britney sure hit a wall.. But, like I said, if she just accepts being a regular person, and picks a decent guy that likes her and her kids, she'll be fine.
Not a chance it'll happen, though.. so we get to watch the meltdown.
