Kate Hudson and Muse frontman Matthew Bellamy, her fiance, have named their newborn son Bingham Hawn.

The baby was born July 9, but the couple reportedly spent a few days deciding on a name. Bellamy Tweeted Thursday:

    "So happy! Just had a baby boy, Bingham "Bing" Hawn Bellamy. Born 7Ib 12Oz, on 9th July. ... Mum and baby are strong and healthy. Mum was a warrior, Bing popped out after 4.5 hours of intense pushing!"

This is the first child for Matthew, so he might not know that 4.5 hours isn't all that much ... but congrats to the happy fam!

As for the real meaning behind the name, Bellamy explained via Tweet: "For those wondering, Bingham is my mum's maiden name and Bing Russell was Kurt's dad. Family connections all round!"

Bellamy, 33, and Hudson, 32, began dating in spring of last year. Hudson announced in January that she was pregnant, and the two became engaged in April.
