Britney Spears' first husband Jason Alexander claims the pop superstar has had cosmetic surgery on her stomach following the birth of her second child in September.
Alexander and Spears were childhood friends from Louisiana and tied the knot in Las Vegas in 2004, only to have the marriage annulled 55 hours later.
And Alexander believes that Spears is determined to get herself into shape following her recent separation from second husband Kevin Federline, with whom she has two children.
He says, "Britney has to be seen to get out there now and be seen to be looking good and so on. She's doing all that. She's been locked down for two years.
"She had a tummy tuck after the birth of her second child. She's working on all of that. She's worth hundreds of millions -- of course she looks good.
"She has the money to have surgery and nutritionists and get her body back. And now she's focused, she is doing it. She's motivated -- she just got rid of a man."
