Britney Spears -- She's Single Again, Y'all!!

Britney Spears is once again on the market ... she's split from boyfriend Charlie Ebersol.

Sources close to the couple tell TMZ ... Britney and Charlie -- who had been dating for the past eight months -- did not have a messy breakup. It kinda looked like it was because Brit deleted several pics of him from social media, but we're told it was more that the relationship simply ran its course.

As TMZ first reported, when the pair got together -- before their first date, even -- Brit's dad made Charlie sign a non-disclosure agreement ... so don't count on him spilling the beans on the relationship any time soon.

Plus, Ebersol's no stranger to the fame game -- he's a TV producer whose dad is sports media legend/"Saturday Night Live" co-creator Dick Ebersol.
