The 'Want U Back' singer looked gorgeous as she walked the blue carpet at the Los Angeles-based awards ceremony on Sunday evening (11 August).
Cher, 19, has been going from strength to strength over in the US ever since finding fame on its shores following her stint on X Factor's seventh season.
Last night, she walked the blue carpet alongside stars including fellow X Factor-born Brit acts Little Mix and One Direction, wearing a cropped top that showed off her tiny waist.
(See, this year's X Factor hopefuls? This could be you next year! Mingling with stars like Selena Gomez, Lea Michele and Lily Collins!)
Cher's appearance at the glitzy awards show at the Gibson Ampitheatre came as she confirmed her next single will be 'I Wish', featuring T.I.
She tweeted: "Is everyone excited for my new single #IWishFtT.I ??? I can't wait for you all to hear it!!!(:."
It's thought 'I Wish' will be the first track from her second as-yet-untitled album, which is due later this year. It will be the follow-up to 2011's Sticks and Stones which featured singles including 'Swagger Jagger', 'Want U Back' and 'With Ur Love'.
Cher will embark on her US 'I Wish Tour' in September, playing 11 dates across America with US X Factor band Fifth Harmony as her support act.
