Cat Deeley has welcomed her first child into the world!

The So You Think You Can Dance host—who first showed off her growing bump at the Emmy Awards last year—took to Twitter on Tuesday morning to announce that she and her husband, Patrick Kielty, gave birth to a bouncing baby boy last week.

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

Meanwhile, the 38-year-old announced she was pregnant in September. "Exciting news.... Paddy and I are so happy to be expecting our first child in the Spring..... Lucky us," the television presenter wrote on Twitter.

When she attended the Emmy Awards a few weeks later, she told E! News' Giuliana Rancic of her pregnancy cravings, "No, I'm all actually fine. I'm not too bad at all. I'm looking forward though to this week being over so I don't have to wear high heels for a long time. There's been a lots of heels this week."

She added, "I managed to squeeze myself into this Monique Lhuillier gown. We had to let the back out a little bit but everything else is pretty okay. I'm hanging in there."

This is the first child for Cat and her husband, who secretly tied the knot in Rome in 2012.
