The gorgeous TV presenter was joined by husband Patrick Kielty at the BBC Children In Need Gala Lunch on Sunday afternoon (27 October).
Cat looked as beautiful as always in a chic black shirt and printed skirt, teamed with her trademark bouncy, glossy blonde locks.
No wonder Patrick looks so happy!
The TV duo were friends for years before romance blossomed and they tied the knot in an intimate ceremony at St. Isidore's College Church, Rome last year. "I really enjoy married life," said Cat during an appearance on ITV's Daybreak this month.
She then joked: "It's still within the first year and a half! Ask me again in five years time!"
Cat celebrated her 37th birthday last week on 23 October with a trip to the theatre to see the critically acclaimed Book Of Mormon. "Absolutely incredible," she tweeted afterwards. "Amazing writing. Fantastically talented cast!"
The blonde presenter lives in sunny California for most of the year because of her Emmy Award-nominated presenting duties on So You Think You Can Dance.
In addition to her TV career, the British-born star is also an ambassador for UNICEF and recently travelled to Mumbai and the rural towns of India as part of a scheme to help disadvantaged girls and young women. The scheme teaches skills and confidence so women can build a strong future and have their voices heard.
She told ITV's Daybreak: "It was more about a kid growing up it was never different between me and my brother. We were treated the same. It isn't the same there. The programme supplies levels of knowledge for people. It's about education, health care, taking care of your finances, being given a voice so you do speak up… It's about changing things gradually."
Cat is also lending her hand to acting, filming a role in new Hulu comedy series Deadbeat. She plays a medium who can't really speak to ghosts but has built an entire career on claiming she can.
We'll be tuning in!
