Lady Gaga has been added to the list of stars performing at the Oscars.
The Poker Face singer will join the likes of Anna Kendrick, Jennifer Hudson and Rita Ora when she hits the stage at the Academy Awards on 22 February (15).
She announced the big news by posting a video on her Instagram account, but stopped short of revealing what she would be doing at the Oscars.
The big show's producer Craig Zadan says, "Welcome @ladygaga to Dolby stage to appear on the #Oscars for a very special performance. It's been a joy working you, Gaga!"
