CELEBRITY BIRTHDAY LIST FOR TUESDAY SEPTEMBER 6

BELLAMY BROTHERS TO BRITNEY - 'SORRY': The old-school country music duo THE BELLAMY BROTHERS have apologized to BRITNEY SPEARS for claiming that her song "Hold It Against Me" ripped off their 1979 song, "If I Said You Had a Beautiful Body, Would You Hold It Against Me".

The  songwriters sued the Bellamy's for defamation, and now the whole thing has been settled with their apology. The case was dismissed, and no money changed hands.

KARDASHIAN KNEWS: You'll soon be able to get married in KIM KARDASHIAN'S wedding dress -- well, sort of -- a replica, anyway. David's Bridal will be selling two of the star's three Vera Wang gowns next year at about $1600 each.

Meanwhile ... As expected, Kim's ex, RAY-J, has staked his claim for a piece of whatever their sex tape sells for. If you recall, an Tennessee lawyer approached the company who owns the vid last week about the possiblilty of buying the tape back, supposedly to get if off the Internet once and for all. Ray's lawyer sent a letter to Vivid Entertainment reminding them that Ray is part owner of the video, and if any deal is made without his input or approval, he will, quote, "file a motion with the courts [to see that his] rights are protected." In other words, he wants his share should the tape ever sell.

QUOTE/UNQUOTE: "[The backlash has] made me realize I'm really glad I'm doing this, because America really needs to see this." -- CHAZ BONO responding to the criticism about him being on "Dancing with the Stars".

He adds,"It just kind of shows why for me it's important to be on the show, because so little still is known about what it means to be transgender. And there's so many just completely inaccurate stereotypes and thoughts that people have."

BABY POOP: Former SPICE GIRL MEL B. had a baby girl on Thursday night. This is the first child for Mel and husband Stephen Belafonte together, although Mel already has two kids and Belafonte one from previous relationships.
