Kate Hudson and Matt Bellamy's New Baby Boy

Kate Hudson is the proud mother of a "healthy baby boy." The famous daughter of Goldie Hawn gave birth Saturday evening in Los Angeles, a spokesperson confirms.

The new bundle is Kate and fiance Matt Bellamy's first child together. Hudson also has a 7-year-old son with ex Chris Robinson of the Black Crows, named Ryder Russell.

News of Hudson's pregnancy was reported by Us Weekly in early 2011. She met the Muse lead singer several years ago in Australia. While the actress was at one time hesitant to tie the knot again, she apprently had a change of heart, telling the world on the Today show. The turn-around may have come from the $200,000 rock from Bellamy.

Or maybe it is true love. "She's crazy about him -- Kate and Matt are so adorable together," said a source.

Regardless, Hudson has been eager to dish about her pregnancy. In an interview with Marie Claire she revieled, "I love being pregnant. Gosh, I could be pregnant all the time."

She also talked about how it was a little easier this time around. "This is a totally different pregnancy, completely," she said. "It couldn't be more opposite -- With Ryder, I didn't even have a nursery. I didn't really have a house until I was seven months pregnant."

The happy couple plans to return London with their new son, while Bellamy records Muse's next album.
