On April 18, Otto was born at Chelsea and Westminster Hospital in London.

Vogue Williams has revealed the name of her newborn son, stating that he “slotted in straight away.”

Otto James Matthews is the name given by the Dublin native and her husband Spencer Matthews to their newest arrival.

Otto was born on April 18 at Chelsea and Westminster Hospital in London.

“We feel very fortunate and really blessed – we couldn’t ask for better kids,” Spencer told HELLO! Magazine in a new interview.

“It’s always been our intention to have a big family and we are very lucky that we have been able to do that.”

Vogue continued, “Her beautiful new kid has instantly blended into life with their two other children, Theodore and Gigi, without hesitation.”

“Otto slotted in straight away. The kids love him and we are obsessed with him. Theodore and Gigi love playing with each other and I think that Otto’s going to be another little member of their gang. It’s really lovely to see.”

The couple recalls the emotional moment they met their son for the first time following a routine birth in the interview.

“It’s amazing when you see your baby for the first time because you’re dying to see what they look like and you’re dying to hold them. It’s just really exciting and emotional,” Vogue said.

“It felt great and we were delighted that he was healthy and safe. It was a feeling of immense love,” Spencer added.

And the baby’s resemblance to his father was immediate. “I mean, there’s none of me in there,” Vogue laughs.

“If I had been shown this baby and had to choose which one was mine, I would never know because he’s just the spitting image of Spencer.”

“I heard somebody else’s child called Otto a couple of years ago and the name always stuck,” Vogue said.

“I just loved it. I think Otto James together sounds really cool.”

With a touching Instagram post earlier this month, TV host Vogue announced that she had given birth to a gorgeous baby boy.

“My sister asked Theodore if he wants to have a brother or sister and he replied: ‘A brother! I don’t want a sister, I already have a sister.’

“So he’s delighted,” Vogue told HELLO!.

“It’ll be the more the merrier,” the podcast host said when questioned about growing their family.

“Theodore and Gigi absolutely love each other, they’re always playing together.

“My sister Amber is my best friend and I want the three of them to be best mates.”
