Popped tart BRITNEY SPEARS is hiding a secret that may trigger backlash from her gay fans.

The ENQUIRER has discovered the singer, 31, opposes gay marriage and sources say her management team is desperate to keep her views under wraps despite a recent slip-up.

“Britney has worked with and danced with a LOT of gays over the years,” a close source told The ENQUIRER.

“She’s never been homophobic but she doesn’t support gay marriage because the Bible is against it.”

The “Toxic” thrush leaked her potentially career-threatening opinion during a Twitter Q&A promo-ing her new LP “Billie Jean”.

Asked about her favorite author, Brit named Max Lucado, a controversial San Antonio, Texas-based preacher who penned a 2004 article claiming that homosexuality could lead to “legalized incest.”

Now Britney’s handlers are worried that her off-the-cuff comment will ignite a bomb in the gay community.

“When Britney spouted off about Lucado being her favorite author, I doubt that she even knew about his opposition to gay marriage,” the source noted. “She just shot off her mouth. Now she’s stunned that her remarks have everyone so worried. Her handlers have always promoted her to the gay audience, and they’re scrambling to do damage control.”

The source cites Britney’s upbringing in the Baptist church as the reason for her opposition to gay nups.

“Britney grew up singing in the church and attends the local Baptist church when she’s home in Louisiana,” explained the source. “She says the Bible bans gay marriage and she follows that teaching.”

But Britney’s savvy enough to realize gays are important to her success and has been told in no uncertain terms that her opposition to gay marriage could short-circuit her career, said the source.

“Her handles know what’s good for business,” added the source. “And Britney will never talk about her disapproval of gay marriage in public.”
