The 'R.I.P.' singer confirmed that that she'll take to the stage at the Academy Awards on 22 February to perform her nominated song 'Grateful' from movie Beyond The Lights.
Rita's track has been nominated in the 'Best Original Song' category. 'Grateful' is performed by Rita, with music and lyrics by Diane Warren.
The other tracks nominated in the category are 'Everything Is Awesome' from The Lego Movie, 'Glory' from Selma, 'I'm Not Gonna Miss You' from Glen Campbell… I'll Be Me and 'Lost Stars' from Begin Again.
Last year's winner was 'Let It Go' from Frozen, with Adele's gorgeous Skyfall theme song triumphing the year before.
It's been a good year for Rita so far: as well as getting an Oscar nomination, she's also been recognised at the Brit Awards with a nomination for 'British Video of the Year' for 'I Will Never Let You Down'.
Rita will also make her feature film debut in Fifty Shades of Grey, which is released Valentine's Day.
