BRITAIN'S Got Talent viewers were left gobsmacked last night by an age-defying act.
Fans of the show insisted Krysstal, from comedy duo Brian and Krysstal, couldn't possibly be 71.
When introducing herself to the judges and audience, Krysstal's age was met with surprised looks, with one woman telling a pal: "She looks good for her age."
The full-time funny duo whipped out musical instruments for their performance, with assistant Krysstal proving handy with a harmonica and tambourine.
She wore her hair in golden pigtails and donned a rainbow-coloured sequin jacket.
It all added to her youthful look, while sixty-something Brian didn't look bad for his age either in a smart suit.

The eccentric performance received a red buzzer from Simon Cowell, while Amanda Holden, David Walliams and Alesha Dixon saw the funny side and sent them through to the next round.
