Joining a whole host of celebs in London, Cheryl made sure to do her bit for charity as she took to the phones for broker ICAP's Charity Day.
And, boy did she do it in style!
She very rarely steps a foot wrong when it comes to her wardrobe, and yesterday proved no exception for Cheryl.
Pictured heading into the offices, the 31-year-old was rocking a super-stylish monochrome theme, teaming a white pussy-bow blouse with skin-tight leather trousers and a cool pair of tri-colour heels.
On the beauty front, Chezza oozed glamour, scraping her newly dyed brunette locks up into a top bun and finishing her look with a slick of Hollwood red lipstick.
Inside the 'Crazy Stupid Love' singer got to work manning the phones to try and break charitable deals with financiers across the globe.
And, fighting for a cause close to her heart, Chezza's charity in question was her own, Cheryl's Trust.
Armed with a celeb team to help her raise donations, Cheryl was joined by her BFF Nicola Roberts as well as Sarah-Jane Crawford, Dermot O'Leary and Simon Cowell - making the day a real X Factor affair.
But, despite usually being at loggerheads with her music mogul boss on the show, Cheryl seemed to love having Simon by her side for the occasion, telling one of her Twitter followers she and the 55-year-old "make a good team".
Following her stint on the trading floor, she tweeted: "Thank you to everyone who came out to support me and every deal we made at @ICAPCharityDay ! It means the world."
This weekend, Cheryl will rejoin Simon, Dermot and co for the X Factor semi-finals on Saturday night.
Last week, Cheryl's last act in the competition, 17-year-old Lauren Platt, nearly missed out on her semi-final place as she found herself in the bottom two alongside Louis Walsh's final group Stereo Kicks.
Following their sing off, the judges were torn on who to save, with Simon sending the vote to deadlock. But, luckily for Lauren, Stereo Kicks were sent home after it was revealed they had received the fewest public votes.
And, Louis was not happy!
Out of the X Factor title race now he has no acts left in the competition, Louis has since said he will "never let Simon forget" sending the boyband home.
Joining Lauren in the semi-finals are Simon's two acts - Fleur East and Ben Haenow - and Mel B's remaining boy, Andrea Faustini.
The X Factor continues this Saturday 6 December at 8pm on ITV.
