The singer, 30, teamed black and white with stripes when she arrived at the annual music event at Wembley Arena on Saturday (21 June).
The stunning X Factor judge chose a white tailored crop top with black striped sleeves which showed off her teeny tiny midriff.
She teamed the top with black trousers, which had white stripes down the side and a white belt.
Stylish Cheryl choose to wear contrasting heels with black, nude and red detail - which we love!
The 'Call My Name' star wore her lightened hair sleek and straight, and accessorised with a chunky gold necklace.
Cheryl has teamed up with Tinie Tempah for her latest track, 'Crazy Stupid Love', which will be released on 27 July. She was due to perform the song at the Summertime Ball.
On Friday night's The Graham Norton Show, Cheryl Cole revealed the real reason she had a huge rose tattooed on her bum.
She admitted she drew up a list of things she wanted to do after recovering from malaria in 2010.
She said: "After I had malaria I created a '****-it list' because life's too short and the tattoo was on the list."
Asked about how much she spent on the design, Cheryl said: "He's an exceptional artist and he was worth it. It was in the £1,000s, probably the cost of a small car."
