We're always fans of Sarah-Jane's chic daytime style, but she proved she's got what it takes in the evening wear department too while taking to the red carpet at the prestigious event.
Showcasing her unique sense of style, the Xtra Factor presenter wowed in a designer dress by Antonio Berardi with an interesting asymmetric half and half bodice, with one side featuring an electric blue sleeve and the other side boasting a sparkly silver strapless design.
Her fancy frock also had a figure-hugging black pencil skirt which fell just below the knee and showcased her enviable curves perfectly.
With such a dramatic outfit the starlet kept the rest of her look relatively simple, topping her pins a pair of pointed ankle cuff heels by Kurt Geiger.
The brunette beauty paired her jet black manicure with a couple of dainty silver bangles by Pandora, styling her new lengthy hair extensions in tumbling curls before finishing her look with her signature pillar-box red lipstick.
Sarah-Jane wasn't the only X Factor star at the event either - her boss Simon Cowell was there with his girlfriend Lauren Silverman and judge Cheryl Fernandez-Versini was in attendance too, smouldering in a lace blue dress.
And it looks like Sarah-Jane got to spend a bit of quality time with Chezza at the event, posting a picture with her chum while adding the caption: "A beautiful night last night, hanging with my gorgeous girl @CherylOfficial #PrideOfBritain."
