While we normally spot the So You Think You Can Dance presenter wearing her honey blonde locks in loose, flowing waves, she's now proved she can totally nail a fab updo too.
Stepping out at the 66th Annual Primetime Emmy Awards in Los Angeles on Monday (25 August), Cat turned heads with a stunning bridal-style hairdo.
Her locks were curled and pinned up away from her face which created an elegant silhouette while also showing off her sparkling diamond earrings.

We turned to stylist to the stars Richard Ward, who gave us an easy step-by-step guide to recreate her look...
1. Start by using a wide barrelled hair tong to create the volume and curls. Use Richard Ward Keratin Bulking Spritz, £5.99, to hold the curls for a look that will last all night. Brush out the curls and focus on backcombing the top and middle sections of your hair - this will add the height and texture needed to maintain the look.
2. Twist the front sections of your hair (the fringe area) back towards the crown of your head and pin accordingly, creating a small quiff-like shape for volume. Spritz with hairspray for maximum hold.
3. Working with the curls, twist small sections of your hair and follow the curl round, securing into place with bobby pins. You need to mimic a swirl-like shape and continue to do so with all of your hair to add volume and texture to the back of your head.
4. Continue to build up the curls at the back of your head, focusing on the centre all the way down to the neck. Spritz a good and strong hairspray all over your hair. Finish with an argan oil-based product to add that extra bit of glamour and shine - the best way to perfect a red carpet look.
