Britney Spears is facing more embarrassment after failing to get a photographer she hired for a family photo session to sign a confidentiality agreement. The troubled pop superstar invited Dani Brubaker into her California home last week (ends07Dec07) to take a holiday photograph of her and her two sons Sean Preston, two, and Jayden James, one. The images were meant to be for Spears' personal use only - but shortly after the snaps were taken, Brubaker released a press statement bragging about the private shoot. And the intimate family pictures could now end up being sold off, because Brubaker was never asked to sign a privacy contract. 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 have yet to comment on the situation.
