Vogue Williams shares adorable snap of lookalike son Theodore (2)

The model posted a photo of her son, who bears a striking resemblance to his superstar mum, posing in a very “grown up” khaki jacket.

Taking to Instagram, the 35-year-old wrote: “How is my little baby 2 and a half already! He looks so grown up, I love him I love him I love him.”

Theodore is Vogue’s first child with Made In Chelsea’s Spencer Matthews, and the couple welcomed their adorable daughter Gigi back in July.

Speaking on a recent episode of the couple’s podcast Spencer & Vogue, the Dublin native revealed their plans to have more children in the near future.

She said: "Spenny and I, we’ve said that we want four kids, now I think definitely three, I’m like on the fence about the fourth with all this carry-on.”

Her husband Spencer added: “Well, fortunately, we don’t have to worry about it for at least three years,” to which Vogue clarified: “That’s the fourth.”

Spencer joked: “There’s your mind going into overdrive again. Worrying about the fourth kid before we’ve had the third.”

Vogue then shared that Theodore and Gigi may have a new brother or sister soon.

She said: “We’ll have the third quite soon I would think.”
