Kate Hudson has finally given birth to her second son with her fiancé, Muse frontman Matthew Bellamy. The actress, who also has a son, Ryder, 7, with her ex-husband Chris Robinson, welcomed her second child on Saturday night, a source confirms. She began dating Matthew Bellamy early last year, and the couple announced their engagement in April. She also celebrated a baby shower in the same month, with a number of famous actors and singers attending the shindig. Kate Hudson, who has been in relationships with New York Yankees Third Baseman Alex Rodriquez and reportedly even with actor Owen Wilson, acted in two movies this year- ‘A Little Bit of Heaven’ and ‘Something Borrowed’. Matthew Bellamy is relatively unknown in Hollywood, but came to the forefront of media priorities after he started dating the high-profile Hudson. He is the lead singer of the popular alternative rock band Muse, and has won several awards for his music and concert performances. He is from London. Muse won the Grammy Award for Best Rock Album in 2011. Matthew Bellamy famously dedicated the win to Kate Hudson, who was then his girlfriend. Kate Hudson and Bellamy have not announced any marriage details, or dates for when the wedding is to occur.
