Taking a break from X Factor judging duties, the singer jetted off to LA to appear at the star-studded ceremony on Sunday, 16 August.
Rita looked gorgeous in a fitted red silk suit – not a look many could pull off but, as always, she totally nailed it. She even matched her hair to her clothing, adding a touch of reddish pink to her poker straight blonde locks.
She teamed with gorgeous Mr Eastwood – the actor son of Clint Eastwood – to present the 'Choice Drama Movie Actress' award to Chloe Grace Moretz.
As well as filming the new series of X Factor, scheduled to start on ITV this autumn, Rita has been working on new music, most recently a collaboration with Chris Brown called 'Body On Me'.
It follows her hit single 'Poison', which reached number three in the UK, and is the first song taken from her upcoming second album, which has yet to be named.
