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

He added, "For those wondering, Bingham is my mum's maiden name and Bing Russell was Kurt's dad. Family connections all round!"

The couple announced in January that they were expecting a baby together. They got engaged in April.

Hudson, 32, and Bellamy, 33, welcomed Bing on Saturday in Los Angeles. The actress also has a 7-year-old son, Ryder, from her marriage to Black Crows frontman Chris Robinson. This is Bellamy's first child.
