Sir Paul McCartney was joined by his glamorous fiancee and a host of A-list celebrities at the world premiere of his first-ever ballet score in New York.
The former Beatles star, 69, confessed he was "quietly confident and nervous" before the debut of Ocean's Kingdom, which was performed by the New York City Ballet at Manhattan's Lincoln Centre.
Sir Paul seemed in high spirits as he took to the red carpet and posed for photographs with Nancy Shevell - who he is soon to marry.
They were joined by a host of A-listers including his daughter Stella McCartney - who worked on the costumes for the production - Sex And The City star Sarah Jessica Parker and actresses Naomi Watts and Liv Tyler.
Sir Paul, who has worked on other classical works including his Liverpool Oratorio, took on the project after meeting the NYCB's ballet master in chief, Peter Martins, last year at the School of American Ballet's winter gala.
He revealed he saw it as "a challenge" as he had never before written an original orchestral score for dance.
The music legend said of his involvement: "Trying to write something that expressed an emotion was very interesting - so you have fear, love, anger, sadness to play with, and I found that very interesting and challenging but great - I'm really glad I accepted."
He added: "I enjoy writing music full stop, so whether it's an orchestra or rock, I immerse myself in it.
"I'm a very enthusiastic person so I enjoyed the process - I didn't really find it too difficult. What was interesting was writing music that meant something expressively rather than just writing a song."
