Like most things in her life, Britney Spears' private family photo shoot has turned into a public affair because she failed to get the photographer to sign a confidentiality agreement.

Dani Brubaker was invited into Brit’s California home last week to take a holiday photograph of the pop mess and sons Sean Preston, two, and Jayden James, one, for her personal use only.

Well, she may need something to remember them by if K-Fed gets full custody.

Brubaker has since released a press statement bragging about the intimate shoot – and there are fears the pics could now be sold to the highest bidder because no contract was in place.

A source tells MSNBC's The Scoop, "She (Brubaker)'s just another person in a long line of people trying to profit from Britney Spears.

"Britney had no confidentiality agreement in place, so this photographer was able to tell the world that this photo shoot, which was meant to be a sweet family affair, not a publicity stunt, took place.

"(Spears) was choosing a photographer who had no reason to be faithful to Britney. Who knows whether Dani will turn around down the road and sell the proofs. It shows that there is no one advising this poor girl."

Representatives for Brubaker are yet to comment.
