Britney Spears may have yet another reason to go to the courthouse.

Sources exclusively reveal to PageSix.com that Britney is planning to sue photographer Dani Brubaker. Brubaker, who took family portraits of Brit and her sons Sean and Jayden in November, recently sold the photos to OK! magazine for a reported fee of “one million dollars.”

Britney will likely hire top legal litigator, Howard Weitzman to sue Brubaker for selling the pics. They will claim that while Brubaker didn’t sign a confidentiality agreement and has the copyright to the images, there were numerous e-mails and text messages that explicitly state the pictures were never to be made public.

In fact, when she was approached by media outlets about the pictures in December, Brubaker issued a press release stating that her “integrity wasn’t for sale,” and that despite having been offered a half a million dollars for the pictures at the time, she would not budge. PageSix.com learned, however, that things had changed when her manager became involved, and struck a deal with OK!.

Our spy tells us that since their appearance in OK!, the pics have been removed from Brit’s house, because she felt like she had been betrayed and “kicked in the gut by Dani.” When Brit’s camp finally got through to Brubaker (after the deal with OK! was done), we are told that the photographer offered no apologies for selling the pictures.
Maybe that’s because she has said she will donate the proceeds to a children’s charity. There is no confirmation of this having taken place yet.

Regardless of Brubaker’s intentions, our source says that “all legal options are being explored at this time. Brubaker must be dealt with, and Britney will absolutely proceed in the very least to sue her.”

Calls to Brubaker’s publicist and Howard Weitzman were not immediately returned.
