Barbra Streisand and Kris Kristofferson reunited for ‘A Star Is Born’ duet

They performed “Lost Inside of You" from the 1976 film.

Barbra Streisand gave the crowd at London’s Hyde Park a treat on July 7, when she reunited with her “A Star Is Born” co-star Kris Kristofferson on stage.

The two opened the 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 favorite leading men.”

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

Then they sang “Evergreen.”

You can see a clip from the performance in a video posted to the Monkeytail Studios YouTube channel. Kristofferson joins Streisand on the stage around the 8-minute mark.

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.”
