A Star Is Born actors Bradley Cooper and Lady Gaga will perform on the Oscar-nominated song "Shallow" at the 91st Academy Awards. The Academy of Motion Picture Arts and Sciences tweeted the news on Friday, writing simply: "Cooper. Gaga. ‘Shallow'. Oscars", reports ew.com

The move was widely expected, and means that four of the five nominees for Best Original Song have now been confirmed for performances during the ceremony: "Shallow", "I'll fight"; "The place where lost go" and "When a cowboy trades his spurs for wings".
