Britney Spears Flaunts Her Toned Abs After 'Finding' Her White Booty Shorts

Britney is showing off her toned body with her latest Instagram.

The pop music icon took to social media Friday to show off her bod crammed into tiny white booty shots while at her gym. She paired them with a pink sports bralette and blue tennis shoes.

"Found my white booty shorts," Spears wrote on the caption, sharing the image with her 19 million followers. The singer also added four winking emojis for effect.

The image showcases the artist's toned arms and legs, and perfect abs.

Spears made headlines earlier this week as she and ex-husband Kevin Federline continue to negotiate child support after he demanded more money, citing her recent success.

Federline, who was married to Spears from 2004-07 and with whom he has two sons, requested in February for an updated child support arrangement after Spears' Las Vegas residency brought in more than $137 million in its four year run.

When Spears ignored his request for more than $20,000 to support sons Jayden and Sean Preston, Federline reportedly contacted her father, Jamie Spears, and was again denied the extra funds.

But a source told Us Weekly that Spears and her team sent an updated child support proposal following her ex's requests, which Federline "flatly rejected."

"Jamie and Britney Spears sent a response to Kevin's request for an increase to his child support payments to his lawyer, Mark Vincent Kaplan. Kevin has flatly rejected it," the insider said.

"Kevin truly wanted to try and settle the child support payment increase without getting the courts involved out of respect for Britney, and of course, their two sons," the source added.

But, according to the insider, when Federline was sent the proposal that was offered to him by Spears' team, the father came to the decision that the child support dilemma may need to be resolved in court.

Federline is now reportedly asking for "a once yearly income and expense declaration from Britney including most recent tax returns filed" and is looking to come up with a new number based on those requests.

While Spears has not given in to her ex's full requests, the insider said that the financial battle has taken a toll on the 36-year-old pop star.

"This is causing Britney a tremendous amount of stress [because] Kevin does indeed have full physical and legal custody of the boys. She just wants this resolved as quickly as possible," the source said.

Hopefully the gym time is helping with the stress.
