But could Sirine have competition in the form of a drumming granny?
76-year-old Crissy Lee delivered this year’s most surprising audition yet, unleashing her awesome drum skills to Queen’s ‘We Will Rock You’, Aerosmith’s ‘Dude (Looks Like A Lady’) and Europe’s ‘The Final Countdown’.
Crissy also scored four yeses from the judges, with Cowell admitting, “I really thought, ‘Oh God you’re gonna be a really bad comedian, I’m gonna have to pretend to like you because of your age. Then you did that, and I think that’s what this show is all about — surprises, talent.”
Cowell added that he would “love to see [Crissy] in the finals” – and it seems viewer at home agreed…
“For me, the fact that you are  and still rocking out and still look cool, and are still doing something you’re passionate about, I find that really inspiring and I think that makes you even more amazing,” agreed Alesha Dixon.
