The three artists are in the running in the category of the best song for this 94th edition of the Oscars, alongside Lin-Manuel Miranda and Diane Warren whose works will also be played during this ceremony.
The queen of pop Beyoncé wrote the ballad "Be Alive" for the film "The Williams Method", devoted to the rise of tennis champions Serena and Venus Williams and in which actor Will Smith plays their coach father.
According to the specialized magazine Variety, the star will perform her title live from the tennis courts of Compton, an underprivileged district of the suburbs of Los Angeles, where the Williams sisters made their debut.
Asked by AFP to confirm the information, the organizers did not respond on Tuesday evening.
Billie Eilish and her brother Finneas will play "No Time To Die", a tube specially composed for the latest James Bond.
Van Morrison, who wrote the song "Down to Joy" for the Kenneth Branagh film "Belfast", was also invited to perform during the Oscars evening, like his competitors.
But "he won't be able to attend the Oscars because of his concert dates," organizers said.
The 76-year-old singer is performing in England at the end of March before arriving next month in the United States to continue his tour.
Van Morrison has in the past criticized loud and clear - and in music with three songs protesting against confinement - the health restrictions linked to the pandemic and said he was opposed to the obligation to be vaccinated against Covid-19.
Positions which for some risked calling into question his participation in the Oscars evening.
The ceremony requires contestants, guests and journalists to be vaccinated, but performers and presenters would be allowed on stage without proof of vaccination provided they pass a rigorous series of tests.
Sebastian Yatra will be present to perform "Dos Oruguitas", a song taken from the latest Disney animated film "Encanto", a title composed by star Lin-Manuel Miranda.
Diane Warren's song "Somehow You Do" was written for the movie "Four Good Days" and will be performed by Reba McEntire.
Diane Warren is an Oscar winner with 13 nominations to her credit but has never won the prestigious golden statuette.
