When it comes to dressing for the TV Choice Awards, a tight-fitting frock and a generous dousing of fake tan tend to be order of the day, so we were thrilled to see that Karen bucked the trend.
The redhead sported a belted lace shift with a slouchy black blazer and ankle boots for effortless glamour.
Karen was on hand to pick up the best family drama prize for Doctor Who, but we reckon she also wins best dressed.
