Cheryl Cole's performance on Stand Up To Cancer failed to hit the right note this evening... any note, in fact.
The Channel 4 telethon started this evening with Cheryl performing new top selling single Call My Name.
But Cheryl's performance was a bit embarrassing for all concerned, after her microphone seemingly failed.
Despite everything being fine in the rehearsals just minutes before the show kicked off, when it came to the final performance no vocals could be heard.
That's live TV we suppose!
Cheryl looked pretty pissed off with the whole thing and we certainly don't blame her.
She still looked absolutely gorgeous though.

Stand Up To Cancer will see a number of both UK and global stars performing and taking part in skits to help raise money for cancer awareness.
As well as Cheryl, there's performances from X Factor champ Leona Lewis and the English National Ballet.
