After ENQUIRER’s exposé of her daring derriere, popped  tart finally dons underwear!

After The ENQUIRER reported that fellow soc­cer moms were outraged when Brit bared her butt at her sons’ game, the 31-year-old singer covered her buns and strapped on a brassiere.

“Thank you, thank you, thank you for putting the word out on Britney,” said an insider.

“Some soccer parents were wondering whether she even owned a bra. But now Britney’s made it a point to be obvious she was wearing one – her tank top was so skintight that the outline of her bra was plain to see.”

AS THE ENQUIRER REPORTED, the “Scream & Shout” singer nearly got banned from the kiddie soccer games after she wore a see-through, flowing sundress – and no undergar­ments – to cheer on Jayden, 7, and Sean, 6, at a match in Cala­basas, Calif.

With one gust of wind, Brit’s flimsy dress became an X-rated spectacle at the March 10 family event.

“Britney is a parent who’s supposed to be watching her kids play soccer, but she comes to the games dressed like a stripper,” sniffed one irritated onlooker.

“It’s inexcusable, and quite honestly, she should apologize to the other parents on the team.”

While the pop princess is no­torious for flashing her private parts, she cleaned up her act for her sons’ game the following week.

“Britney also wore Daisy Duke-style shorts that were still way too short and tight, but at least she’s finally making an effort to cover up on the soccer field,” the insider noted.

The former “X Factor” judge – who’s been dating re­searcher David Lucado, 27, since splitting with former fiance/agent Jason Trawick – was joined by her ex-hubby/ baby daddy Kevin Federline, 34, his galpal Victoria Prince, 30, and their 1-year-old daugh­ter Jordan at the March 17 match.

“It’s about time someone told Britney to cover up,” added the source.

“If she doesn’t learn how to dress appropriately now, her kids may be so embarrassed that in the future they’ll beg her to stay away from their games!”
