He wrote: "BREAKING NEWS: Welcome @ladygaga to Dolby stage to appear on the #Oscars for a very special performance. It's been a joy working you, Gaga!"

And he also shared a snap of Gaga at rehearsals with his team for the big show.

Gaga will join Jennifer Hudson, Anna Kendrick, Common, John Legend, Adam Levine and Rita Ora on the bill at the Dolby Theatre in Los Angeles on 22 February.

She recently performed with veteran crooner Tony Bennett at the Grammy Awards.
