She's a regular on the showbiz circuit and knows all too well that having an outfit change at the ready can be extremely useful. 

Putting her knowledge to good use on Wednesday, Alesha pulled off not one but two stylish appearances as she headed out in London. 

After joining Amanda Holden for the launch of Britian's Got Talent's new series, the singer, 38, slipped into a slinky wrap dress as she made her way to the star-studded Jog On For Cancer charity bash in Kensington.

Certainly dressed for the occasion, Alesha cut a demure figure in a glamorous nude wrap dress that cinched in at the waist with tie up detailing. 

Her sophisticated number boasted a daring thigh-high split and plunging neckline, but the Boy Does Nothing vocalist avoided a wardrobe mishap by teasing a look at her lacy lingerie underneath. 

Alesha drew attention to her enviable pins by sporting a pair of barely-there sandals - that included a see-through strap around the ankle - on her feet.

She wore a long silver pendant on her neck and tucked her raven-hued tresses behind one ear to showcase her stylish hooped earrings. 

The mum-of-one wore her locks in a sleek and straight style and oozed glamour thanks to her flawlessly applied make-up. 

She then added the finishing touch to her ensemble with a slick of nude gloss across her lips.

Seeming in high spirits on arrival to the event - held at Kensington Roof Gardens in aid of Cancer Research UK - Alesha flashed a beaming smile as she struck a pose for photographers. 

Inside the venue she was joined by a bevy of celebrities including Casey Batchelor, Vicky Pattison and Liberty X girls Jessica Taylor, Michelle Heaton and Kelli Young as they enjoyed a reunion. 

The best of the reality TV crowd turned out too and saw a few awkward run-ins between exes Marnie Simpson and Lewis Bloor, and TOWIE stars Megan McKenna and Pete Wicks. 

Alesha's appearance at the event comes after she spent the day with her close friend and fellow judge Amanda Holden as they kicked off the new series for Britian's Got Talent which returns to ITV this Saturday.

Alesha's appearance at the event comes after she spent the day with her close friend and fellow judge Amanda Holden as they kicked off the new series for Britian's Got Talent which returns to ITV this Saturday. 

Alesha stole the show in a fish tail skirt and dramatic crop top that tied together in a bow at the back. 

She will return to the judging panel on the show alongside Amanda, David Walliams and Simon Cowell and recently spoke about the close bond they all have.

Speaking to The Mirror she revealed: 'The banter is unreal.

'Ant and Dec get constantly teased for their OBEs by Simon and it gets fierce when we place bets on who's going to win Britain's Got Talent.

'We're trying to wangle it so the winner gets a holiday.'
