With her parents in tow, the 38-year-old headed out for a spot of retail therapy across the pond, covering up her growing tum in a stylish printed maxi dress.
Keeping all us baby bump watchers at bay, Cat seemed keen to keep her bump under wraps while she still can, even covering her stomach with her handbag when being photographed.
That didn't stop the British born TV presenter looking totally gorgeous, though, and the mum-to-be was all smiles as she left Barney's Beverly Hills stars. Starting on that baby wardrobe early, perhaps?
Cat is expecting her first child with husband Patrick Kielty and announced her pregnancy last month. The starlet took to Twitter in early September, revealing to fans she and Patrick are set to become parents in Spring next year.
She tweeted: "Exciting news.... Paddy and I are so happy to be expecting our first child in the Spring..... Lucky us."
Their baby joy comes three years after Cat and Patrick married. They wed in Rome back in 2012.
Earlier this month, Patrick revealed how he finally managed to sweep Cat off her feet. The pair had been close friends for many years before they actually started dating.
When asked if there was a moment that turned their friendship into something more, Patrick gushed: "There was a moment... it was her birthday. She was in LA... obviously LA is eight hours behind, so I text her happy birthday from a little Irish pub. It was about 2 o'clock in the morning, near closing time. She said it's just a shame you're not in LA, I'm having a lunch tomorrow and I said I'll be there.
"So I got up at five, jumped on a six o'clock flight from Ireland, got into Heathrow at seven, jumped on a twenty to ten flight, got in at quarter past one and walked into the Beverley Hills hotel. She fell off her chair and we've been together ever since."
