A kitten for Cat! The So You Think You Can Dance family is about to add one more to its troupe: Longtime host Cat Deeley is expecting her first child with husband Patrick Kielty.

Deeley, 38, announced the news via Twitter on Thursday, Sept. 3. "Exciting news....Paddy and I are so happy to be expecting our first child in the Spring....." she wrote. "Lucky us."

A short time later, she tweeted a text message exchange between her and her producer. The exchange showed a text poking fun at some of the dietary restrictions for pregnant women. "Jeff and I are going to a soft cheese and shellfish party. Want to come?" it read.

Deeley shared the pic on Instagram, writing, "My producer's response to our exciting news! I laughed till I cried! You don't want to know my reply!"

The British TV star and her comedian husband said "I do" back in 2012 in a surprise ceremony in Rome. A source told Us it was "the most beautiful, gorgeous, chic, and romantic wedding," and the hostess herself later gushed that it was the "best party ever."
