Cat Deeley welcomes baby boy

Patrick & Cat

Cat Deeley has had a baby boy.

The 'So You Think You Can Dance' host took to Twitter on Tuesday morning (19.01.16) to tell fans that she and husband Patrick Kielty had welcomed their son into the world last week.

She tweeted: "Beyond delighted to announce the birth of our baby boy last week. All doing well & we couldn't be happier... 3 really is the magic number!"

Cat, 39, and Patrick, 44, have previously had a transatlantic relationship, with her based in the US and her spouse dividing his time between London and Belfast.

But Cat revealed in a recent interview that they are looking forward to giving their unborn baby an experience very different to their own childhoods.

She told Closer magazine: "We're going to ensure we take the baby back home to visit our families as much as possible but, for now, we're happy here in LA and are excited to bring up our child with an outdoors lifestyle.

"They're going to experience the LA sunshine Patrick and I never got to experience."

Cat was extremely open during her pregnancy, and admitted as she got to her final trimester last year that she wasn't having any cravings - but Patrick was!

She told Closer magazine: "I've always followed a relatively healthy diet and never had junk food cravings.

"The only thing I'm really missing right now is Champagne. I love a glass before a show or when I'm out for dinner.

"Patrick, on the other hand, seems to be having cravings for me. He's been eating lots of ice cream and saying it's out of sympathy."
