The former Waterloo Road actress, 25, showed off her perfect pins in the short frock, which featured sequins and a plunging neckline.
To give it some extra oomph, Chelsee's outfit also stood out from the crowd thanks to its sheer grey train, also trimmed with sparkles.
Chelsee definitely stuck to the dresscode for the charity bash and completed her look with a pair of statement earrings, an oversized silver clutch and platform Louboutin peep-toes.
Prior to the bash, Chelsee told her Twitter followers: "It's a ball thing! Finally able to wear my @TheDollsHouseNQ dress out!"
She also shared a gorge picture of herself wearing the head-turning dress while in the very luxurious looking loos at the Lowry Hotel!
The Mirror Ball raises money for Forever Manchester, which support people communities in Manchester, and Friday's event raised a staggering £40,000.
