Britney Spears at the American Music AwardsBritney Spears‘ first husband (if only for 55 hours) Jason Alexander has revealed that Britney had a tummy tuck to help get her back into shape after giving birth to her second son in September.

It’s been a busy two and a half months for Britney since Jayden was born: in addition to filing for divorce from second husband Kevin Federline and reinventing herself as a panty-less party queen, she lost over 26pounds (nearly 2 stone) in weight - but now Jason is claiming she had a little help with that.

According to the Sun, he revealed recently: “She had a tummy tuck after the birth of her second child.”

“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.”

“Britney has 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.”

He also added to the rumours that Britney wanted a threesome with Kevin Federline and another girl. He claims: “all beautiful girls like other girls in some way. All girls are attracted to other girls. She found other girls attractive, yes, but we never did anything about it. That’s not to say that I don’t know anything about threesomes.”

Jason is currently writing a book about growing up in Louisiana with Britney and about their short, later annulled, marriage in Las Vegas.
