Legendary diva Barbra Streisand will sing at the Oscars next month, her first Academy Awards performance in 36 years, organisers say.
Streisand has earned two Oscars, but has only performed at the top Hollywood awards show once before, in 1977 when she sang the winning song from A Star Is Born.
"In an evening that celebrates the artistry of movies and music how could the telecast be complete without Barbra Streisand?" said the show's producers Craig Zadan and Neil Meron.
"We are honoured that she has agreed to do a very special performance on this year's Oscars, her first time singing on the show in 36 years," they added in a statement.
Streisand - whose latest movie, Guilt Trip, came out in the US last month - won her first Oscar for Best Actress in Funny Girl 1968, and her second for best original song for A Star is Born in 1977.
She was nominated for best actress in 1973 for in The Way We Were, for producing 1991's The Prince of Tides, and for co-writing the original song I Finally Found Someone from The Mirror Has Two Faces (1996).
Others already confirmed for the February 24 Oscars show include British songstress Adele, who will sing her 007 theme tune Skyfall, and foul-mouthed teddy bear Ted, with his big-screen sidekick actor Mark Wahlberg.
