Britney Spears 'Spending $22,000-a-Month' to Get Back in Shape

Britney Spears is spending $22,000-a-month in a bid to lose weight, it has been claimed.

The Toxic singer has already lost a stone on her diet and exercise regime, which sees Britney spend $10,000-a-month on a nutritionist and diet supplements; $8,000 on a personal trainer; and $4,000 on a private dance choreographer.

A source reveals, "She limits herself to 1400 calories a day with one 'cheat day' where she'll treat herself.

"She also changed the way she eats, trying to have only two thirds of what is on her plate. It's all about portion control and fresh food now. And lots of water in place of Red Bull."

Spears, 26, has taken on some of Victoria Beckham's diet tips, eating plenty of steamed fish and snacking on edamame beans. She also endures intensive work-outs with Pussycat Dolls' personal trainer James Van Daff as well as three-hour dance classes six times a week.

The source added to Britain's Closer magazine, "Britney piled on a lot of weight earlier this year. She was so stressed about the custody case and her medication for her bipolar disorder also made her put on weight. She was tired of being flabby and wanted to do something about it.

"Britney is so proud of herself because her ab muscles are back.

"She's feeling better than she has in ages."
