Cat, who is currently visiting the UK from America, was pictured in a gorgeous LBD at the WGSN Global Fashion Awards.
The So You Think You Can Dance? presenter was all smiles as she posed for pictures at the bash, which was held at the Victoria & Albert Museum in London.
Cat teamed her black long-sleeved dress with a simple pair of black court shoes and she kept her blonde hair loose and in slight waves.
Finally, Cat - who is married to Irish comedian Patrick Kielty - topped off her getup with her dazzling engagement and wedding rings.
Earlier this week, Cat was joined by her hubby Patrick at a Children In Need Gala Lunch, held at the Savoy Hotel in London.
