Singer, actress and double Oscar-winner Barbra Streisand is to perform at the Academy Awards for the first time in 36 years, organisers have announced.
The 70-year-old last sang at the Oscars in 1977 when she performed Evergreen from A Star is Born, recipient of that year's award for best original song.
Telecast producers Craig Zadan and Neil Meron said they were "honoured" she had agreed to do a "special" performance.
Adele and Norah Jones are also lined up to sing at the event on 24 February.
The former will sing her James Bond theme tune Skyfall, while the latter will sing Everybody Needs a Best Friend from the comedy Ted.
Both are up for this year's original song prize, alongside tracks from Les Miserables, Life of Pi and the documentary Chasing Ice.
Streisand received her first Oscar in 1969 for her debut acting role in the musical Funny Girl. She shared the award with Katharine Hepburn, recognised that year for The Lion in Winter.
Five years later her theme tune for her film The Way We Were, composed by the late Marvin Hamlisch, won the best song Oscar.
Hamlisch is sure to be remembered at this year's ceremony, giving Streisand the ideal opportunity to reprise their most celebrated collaboration.
"In an evening that celebrates the artistry of movies and music, how could the telecast be complete without Barbra Streisand?" said Zadan and Meron in a statement.
