Judges Mel and Cheryl couldn't resist posing for a cheeky photo on Sunday (3 August) as the audience sat and watched behind them.
Mel said: "Me and home girl Cheryl acting up on set right now, wow it's been along long day."
It was a long day indeed, as Mel, Cheryl and fellow judges Simon Cowell and Louis Walsh, were still auditioning hopefuls until after midnight!
Posing for a photo with Louis, former Spice Girl Mel said: "Yep 12.30am and we are still auditioning X Factor."
In case you were wondering where Simon was in all the festivities, he did get involved. On Saturday (2 August), the music mogul was spotted leaning into a group selfie!
The eleventh series of The X Factor will hit screens later this month and, with Simon and Cheryl on the panel, it'll mark their first return to the show since leaving in 2011. Watch the trailer here!

Meanwhile, new Xtra Factor host DJ Sarah-Jane Crawford, who is replacing old host Caroline Flack, looked elegant and chic as she greeted crowds in London.
