The Hot Right Now hitmaker turned heads in a figure-hugging gown that clung to her toned physique.

But all eyes were certainly on her best assets as the low-cut dress flaunted her masses of cleavage. 

The London-born singer just about kept her buxom bosom in check as she strutted her stuff on the red carpet. 

When she turned to the side, cheeky Rita revealed that she went knickerless for the star-studded awards, thanks to a cleverly placed lace panel. 

Rita was a picture of elegance in the chain-mail style gown which she complimented with a sky-high silver heel.

The popstar kept the rest of her look understated, teaming a delicate smokey eye with a slick of dark-nude gloss. 

She was later caught cosying up to boxer Connor McGregor as they shared a drink. 

Rita, with her arms folded across her chest, pushed her bust together for the glamorous shot. 

Holly Willoughby cut a classy figure at the awards when she arrived in an all-black jumpsuit.

The 36-year-old kept herself warm in the December weather with a chic silk blazer wrapped around her bare shoulders. 

She added a touch of glam with some seriously sparkly stiletto heels.
