Vogue Williams reveals the name of her newborn baby son in Instagram post

The couple, who are already parents to 3-year-old Theodore and 1-year-old Gigi, welcomed a healthy baby boy on Easter Monday and named him Otto James Matthews.

The couple shared how they chose the baby’s name and said that his middle name was inspired by Spencer’s brother.

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

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

Speaking about how the kids are adjusting to having a baby brother, Spencer said: “We feel very fortunate and really blessed - we couldn't ask for better kids.

“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 added: “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 recalled the emotional moment when they finally met their son.

“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 told Hello Magazine.

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

Vogue took to Instagram on Sunday afternoon to share the first photo of their new family-of-five and said: “Here he is! The newest member of our family… I can’t believe he only arrived 12 days ago, it feels like he’s been here forever.”

She announced that she had given birth to a baby boy with an Instagram post showing Theodore and Gigi having a cuddle with baby Otto.

Vogue wrote: “We are so happy to announce that our beautiful boy arrived safely on Monday evening. Bursting with love he is the perfect addition to our family.”
