Barbra Streisand and Kris Kristofferson reunite for A Star Is Born duet

(CNN) — Barbra Streisand gave the crowd at London’s Hyde Park a treat on Sunday night when she reunited with her A Star Is Born co-star, Kris Kristofferson, on stage.

The two opened the British Summer Time show together, singing ‘Lost Inside of You’, a number from their 1976 version of the movie.

Streisand introduced Kristofferson by telling the crowd to welcome to the stage “one of my favourite leading men.”

“Here’s a song that we sang together in the movie, right? I love this song,” Streisand continued.

Then they sang ‘Evergreen’.

Streisand had hinted about a reunion with Kristofferson back in April on Instagram, when she posted a photo of herself with him, writing, “Stay tuned.”

The show was for a sold-out crowd of 65,000 — the biggest audience she’s performed for since a Central Park performance for 150,000 in 1968, according to Variety.

Kristofferson had performed a set earlier, but the crowd did not know for sure if he would appear with Streisand. Later in the show, Lionel Richie joined her on stage for a duet of ‘The Way We Were.’

Streisand went on to sing, ‘As If We Never Said Goodbye,’ a version of ‘Any Place I Hang My Hat is Home’, ‘Alfie’, ‘Second Hand Rose’, ‘Silent Night’, ‘What the World Needs Now’ and closed the night with ‘The Man That Got Away.’
