Irish TV presenter Vogue Williams shared the news she had given birth to a 'beautiful and healthy' son with a cute post on Instagram.
"We feel truly blessed," she wrote.
Former Made In Chelsea star Spencer Matthews also shared a photo on social media, writing that he "couldn't be more proud" of Williams.
Williams, ex-wife of Brian McFadden, and Matthews tied the knot in June this year after becoming engaged in February.
The pair met when they appeared as contestants on snow sports show The Jump in March 2017.
