Kate Hudson has named her new son Bingham Hawn.
The actress and her rocker fiance Matt Bellamy welcomed their little boy into the world on Saturday (09.07.11) and while his moniker was initially kept under wraps, the Muse frontman has now announced it.
Writing on his twitter page, he said: "So happy! Just had a baby boy, Bingham 'Bing' Hawn Bellamy. Mum and baby are strong and healthy. Mum was a warrior, Bing popped out after 4.5 hours of intense pushing!"
While it is not known where they got the idea of Bingham from, it is thought the tot's middle name pays homage to Kate's mother Goldie Hawn.
Following his birth, the couple asked for "Celebration trees" to be planted for their son, just as they did at Kate's baby shower.
Matt and Kate - who has a seven-year-old son, Ryder, with ex-husband Chris Robinson - plan to spend the next few weeks at the rocker's London home while Muse record a new album.
