Madonna: No fan of Gwen's L.A.M.B.

Madonna has a lot of high-profile friends: Gywneth Paltrow and Stella McCartney, to name a few. But one celebrity Madonna may have lost as a friend is Gwen Stefani.

According to London's Daily Mail, Stefani recently sent Madonna a package for her adopted son David. The package contained a number of outfits from Gwen's L.A.M.B. children's clothing line. Gwen's son Kingston is often seen in the children's line, while L.A.M.B.'s women's line is a big hit among starlets like Britney Spears, Lindsay Lohan and Nicky Hilton. Madonna, however, is apparently not a fan - she turned down the package.

An insider told the Daily Mail, "[Madonna] politely thanked Gwen but called her to say she and Guy disagree on the children wearing clothes that blatantly promote people's personal brands. She was touched but wasn't sure if Gwen was secretly trying to get publicity by sending her the gift."
