The former Girls Aloud star went for understated and sophisticated on Tuesday (24 June) as she joined her fellow judges at the capital's Emirates Stadium to continue whittling through the London talent.
Cheryl, 31, teamed loose black trousers with a cream cropped shirt and oversized gold necklace, keeping her blonde locks straight and smooth.
She's looking pretty bronzed, isn't she? We wonder if Chezza has been out enjoying the summer sunshine as much as we have lately!
Cheryl spent her weekend performing to thousands at Capital FM's Summertime Ball with Vodafone, held at Wembley.
While there, she chatted about her return to X Factor, which will see her judging alongside Simon Cowell, Louis Walsh and Scary Spice Mel B.
"There's a good dynamic on the panel," she said.
Good dynamic? Hmm. We wonder if that means lots of fireworks, animated discussions and disagreements? Hopefully!
Cheryl admitted that she's got her eye on the girls category, which she won with Alexandra Burke in 2008 and also featured her act Cher Lloyd in 2010.
