The TV presenter and now permanent LA resident looked fab after her trip to the hairdressers and, with tresses like that, we can see why she was all smiles!
Pictured leaving Salon Benjamin in West Hollywood, Cat flashed her pearly whites for the camera and headed to her car with a bag of goodies no doubt full of fancy hair products.
She dressed in a smart-casual ensemble of black skinny jeans, a textured navy blue jacket and a pair of black sunglasses.
But of course, we couldn't take our eyes off her shiny blonde hair!
The Birmingham born star, 37, is now back at home in Los Angeles after a fun-filled visit to Philadelphia for work.
While out there, Cat made sure to keep her Instagram followers up to date with her adventures by posting various snaps of herself at restaurants while sampling some extremely tasty looking food.
She also uploaded a short video clip of herself running up the famous steps of the Philadelphia Museum of Art, which feature in the Rocky film series.
Not quite Sylvester Stallone, but we love her enthusiasm!
However, despite all the sight seeing and eating out, it sounds like Cat was missing her husband Patrick Kielty, since she captioned one of her photos in a café: "Suddenly so French.... Parc in Philly. Then back to the sunshine and my love ...."
