Singer Barbra Streisand is to give a rare performance at this weekend's Grammy awards, organisers have said.
The eight-time Grammy winner, 68, is nominated in the best traditional pop vocal album category for her latest record, Love is the Answer.
The awards will be handed out at a Los Angeles ceremony on Sunday.
Streisand will also be honoured this week by the Grammy's charitable foundation MusiCares for her "creative accomplishments and philanthropy".
The singer will appear on Friday at the end of a tribute that will see Tony Bennett, Stevie Wonder and others perform interpretations of Streisand hits.
Streisand rarely performs at public events unless it is for charity and has toured only four times during her five-decade career.
In an interview with the Los Angeles Times, the Oscar-winning actress confirmed she plans to star in and possibly direct a new film version of 1959 musical Gypsy.
Sir Mick Jagger, Eminem, Lady Gaga and Katy Perry are among other artists lined up to perform at this year's Grammys.
Organisers have also announced that US singers Miley Cyrus, John Legend and Kris Kristofferson will present awards at Sunday's event.
Elsewhere Christina Aguilera, Jennifer Hudson and Florence Welch are among artists who will perform a celebration of Aretha Franklin following her recent bout of ill health.
