Kate Hudson and fiancé Matt Bellamy have finally settled on a name for their new arrival.
The baby boy, who was born on Saturday night in L.A. weighing in at 7 lbs. 12 oz, has been named Bingham Hawn Bellamy.
British Muse rocker, 33, tweeted today: '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!'
Soon after, he returned to Twitter to explain the inspiration behind the unusual name.
He wrote: 'For those wondering, Bingham is my mum's maiden name.
'Bing Russell was also Kurt [Russell's] dad. Family connections all around!"
The actress, whose biological father is Bill Hudson, considers Russell, her mother Goldie Hawn's partner of 28 years, a father figure.
Nicknamed Bing, the boy's middle name is also a tribute to Goldie.
Kate, 32, also has a son Ryder, seven, with her ex-husband, Chris Robinson.
The How To Lose A Guy In 10 Days star gave birth shortly before fellow A-list star Victoria Beckham, who also opted for an unusual baby name - Harper Seven.
