Gorgeous baby boy!

Vogue and Spencer on Sunday shared the first snap of their son - and suffice to say he's an absolute cutie. The little one, who arrived on September 5, was heralded into the world via an Instagram announcement that read: "This morning at 3:55am, we welcomed our son into a quiet London hospital. "He is beautiful and healthy. We feel truly blessed." And now the duo - who married in Scotland in August - have FINALLY shared a proper picture of their new arrival... as well as the name - Theodore. Showing off the Hello! magazine cover shoot, Ms Williams, 33, wrote:

"My whole world has changed with the arrival of our beautiful boy Theodore. "The last two weeks have been the best of my life. I am loving every minute of being a mother, even the very sleepy wake up calls at night. "Spencer and I have never felt love like it, Theodore you are our world..."

She furthermore told Hello! magazine: "We are bursting with love. I honestly feel like he has been here forever, he has just slotted into our lives perfectly." And 30-year-old Spencer added: "Every day has new meaning now. It has exceeded all expectation of what I thought it would feel like to be a dad." As for the name, Vogue explained: "We heard the name Theodore one day and both loved it. We thought we would call him Teddy but since he has been born we have stayed with Theodore rather than shortening it." Meanwhile, Theodore’s middle names have special significance: Frederick after Vogue’s late father and Michael after Spencer’s brother who died aged 22 in 1999 after reaching the summit of Mount Everest. Vogue furthermore told the publication that she was on the verge of having an emergency C-section on September 5, but was ultimately able to give birth naturally with Spencer cutting the cord. He explained: "Obviously Vogue did all of the hard work and I have nothing but love and respect for how she dealt with it all in the most admirable way. I could not be more proud of her."
