TMZ obtained a letter, sent by the owner of YouPorn to the Editor of Closer Magazine -- which published the topless pics of Kate.
In the letter, YouPorn honcho Corey Price says he wants to buy the "intimate footage" the Closer Editor has been yakking about. Price writes, "We feel very confident that we can show this footage legally, and would like to make you aware that we have an 'open checkbook.'"
The Closer Editor has said she held back in publishing the "intimate" pictures, although she didn't say why.
