Cat, who is visiting London for a short break, looked radiant in a chic blouse and an animal print pencil skirt. The blonde beauty wore her trademark, glossy locks loose over her shoulders and showed off her tanned legs.
The So You Think You Can Dance presenter completed her look with a leather black clutch and dainty gold jewellery, and happily posed for cameras. Patrick looked dapper in a navy blue suit as he posed with his arm around his wife.
Cat and Patrick, who have been married for just over a year, flew back to London to celebrate Cat's 37th birthday with a trip to the theatre last week.
"Birthday treat..... Book Of Mormon...... Absolutely incredible. Amazing writing . Fantastically talented cast! Xxxx," tweeted Cat on the day.
The globe-trotting couple also recently returned from a goodwill trip to India. Cat, who is a UK ambassador for UNICEF, took part in a scheme to help disadvantaged girls and young women.
The TV presenter was accompanied by her husband on her travels, and the couple documented their trip with a series of stunning photos.
"Jaipur ... On top of the world ..." wrote Cat, next to a particularly touching snapshot of the couple kissing with the city view behind them.
The honeymoon period looks far from over for the lovebirds, with Cat previously saying that married life suits her.
"I really enjoy married life," said the blonde beauty, then joking, "It's still within the first year and a half. Ask me again in five years time."
