The mega-watt smile that made Cat one of the UK's best-loved TV presenters was even wider and, for his part, comedian Patrick looked delighted to have his glamorous wife by his side. Her stunning lacy ensemble may have had something to do with that.
Until now, the couple have kept a low profile since their surprise wedding in September, when they tied the knot quietly in Rome. The ceremony took place in St Isidore's College Church, with Patrick's parish priest Father Gary Donegan officiating. Such was the secrecy surrounding their big day, that some guests only learned about the wedding at the last minute.
At the time, an insider revealed: "It was a beautiful ceremony, just close friends and family. We only found out at the last minute. It was a really perfect day. They've been pals for ages and we all just wonder what took them so long." Those closest to Cat were initially surprised when the blonde's ten-year friendship with Patrick turned into love, and the star herself recently revealed the reason behind her change of heart.
She told the December issue of Red magazine: "I told him I was having brunch with friends here at the Beverly Hills Hotel. He got on a plane to London, then another plane to LA, then he came straight from the airport with his bags, walked in, sat down and had birthday brunch with me.
"And then, when I went to pay for everybody, they wouldn't take my card because it had all been taken care of. That's quite possibly the most romantic thing anyone has ever done for me. And he was just sitting there hanging out with 12 of my friends, making everybody laugh. It was romantic, noble, kind of amazing and pretty hard not to fall in love with him."
Indeed, the bubbly presenter has been radiating contentment since they were first linked after holidaying in February. Soon afterwards the Irishman moved into her Beverly Hills mansion, and rumours of an engagement began to circulate.
These were denied, but it was clearly serious as Patrick hinted last year that it wouldn't be long before he had a ring on his wedding finger. "I think that might be my New Year's resolution... to get married," he said.
