Dani Brubaker, a photographer that Britney Spears hired to take family portraits a few weeks ago, has sold the images to OK! magazine, despite swearing her “integrity isn’t for sale.”

The magazine is running the photos as their cover story with the headline “Last Day With Mommy” — although technically the photos are from November, when Britney still had custody of the two boys, Sean Preston and Jayden James.

Shortly after Brubaker took the photos, she swore up and down to BreatheHeavy.com, a Britney fan site, that she’d never sell them to the tabloids, even though Britney didn’t require her to sign a confidentiality agreement:

The images from the shoots were never available for purchase, although I have been offered upwards of half a million dollars. Recent postings indicate that I profited from these images. Which is not true.

My integrity isn’t for sale. I stand by my statement that “The kids are adorable and are obviously well loved.”

… It’s just so sad to see what the media does to her. Truly makes me sick to my stomach.

There wasn’t ever a temptation, no matter what they offered. What I captured of her and the kids is truly beautiful and I just would not be able to live with myself to see those images in a tabloid.

But sources now say OK! paid more than $1-million for the images.
