Mariah Carey's children have a new baby brother, with a very unusual name.

Mariah Carey’s ex-husband Nick Cannon has welcomed a baby boy, a sibling for Carey’s own five-year-old twins.

Announcing the birth on Instagram, the 36-year-old welcomed son Golden Sagon Cannon on Tuesday.

Alongside an image of himself holding his new baby, Cannon wrote: “Weeping may endure for a night, but Joy cometh in the morning! No matter how hard the world may hit you, God always reminds us of our purpose! #TrueHappiness. Welcome to Earth Son! Golden “Sagon” Cannon 2/21/17.”

It’s the comedian’s first child with former US beauty queen Brittany Bell, whom he is no longer dating.

In announcing the pregnancy on Entertainment Tonight last year, Cannon said the fact he and Bell are no longer a couple does not dispel the excitement surrounding the news.

“It’s outstanding. Honestly they say even in unexpected situations, you still embrace the beauty of bringing a life into this world, because that is what life is all about,” he said at the time.

Cannon married US pop royalty Mariah Carey back in 2008, with Carey giving birth to their twins Monroe and Moroccan in 2011. In August 2014, Cannon confirmed after much speculation that he and Carey had separated a few months earlier.
