The 31-year-old singer flashed her knickers to fans while on stage as she pranced around in a tiny red dress and knee-high black boots.
She might have been singing some of her most well-known tracks but the only thing the audience could focus on was her crotch on show.
Alesha’s fashion faux pas may however drum up some publicity for her upcoming record Unleashed, to follow the 2008 album The Alesha Show.
The raven-haired beauty spoke of the new album in a video on her official website, saying: ‘I’m really excited about the new record.
‘Time is ticking but we’re getting there and we’re nearly ready to come with the album. We’re just mastering it, mixing it as good as it can be for you guys.’
Her new single Drummer Boy, which is her first single to be released from the new album, is set to come out at the end of August.
