The Britain's Got Talent judge looked hot to trot in her two-piece while walking the red carpet ahead of the new documentary screening.
Alesha's fab suit ticks all this season's style boxes with its fierce print, monochrome colour palette and cropped ankle-flashing trousers.
And while we thought her getup would be a super-luxe designer buy, it's actually from high street store The Kooples (although it appears to have already sold out online - boo!)
The starlet let her stand-out suit do all the talking by pairing it with a white vest and completely ditching the jewellery.
She topped her pins with taupe patent courts and flaunted a pretty peach mani, styling her locks in loose tousled curls.
Alesha even got things right on the beauty front, opting for smoky metallic brown eyes and oodles of black liner, plus flawless skin and defined brows.
And for the finishing touch the yummy mummy slicked on a Hollywood red lip.
Looking good, Alesha!
Other attendees at the event included fellow mum Imogen Thomas, who rocked a cute white dress, and Celebrity Big Brother star Casey Batchelor.
