And with the likes of A-lister Liz Hurley - the star of the new sitcom airing on E! - joining her at the showbiz bash, it's no wonder Sarah-Jane made sure to turn up the glam.
We LOVE her gorgeous blue number, don't you?!
Posing on arrival to the event, Sarah-Jane bared her décolletage and flashed those enviable pins of her's in a sassy electric blue dress. Not only did her tulip-style frock feature an off-the-shoulder design, but it also included dainty spaghetti straps too.
Looking beautifully bronzed (thanks to her St Tropez tan!), the 33-year-old teamed her gorgeous outfit with a glitzy pair of pointed silver courts and a big and bouncy blow-dry.
And while Sarah-Jane debuted a slightly shorter bonce not too long ago, yesterday, the starlet was back to sporting her signature tumbling tresses. Parting her raven-hued locks in the middle, the starlet styled her glossy mane into voluminous curls.
On the beauty front, Sarah-Jane made sure to dazzle, dolling up her kohl-lined peepers with gold shimmer and perfectly arched brows.
She added a hint of bronzer just under her cheekbones, finishing her look with plenty of gloss on her pout.
Following her fun-filled evening, Sarah-Jane took to Instagram to tell fans she had had an "awesome night".
She said: "Awesome night hosting #TheRoyals red carpet show for @Eonline & #ENews ... Hanging with the Queen Elizabeth Hurley."
