"Nothing's Gonna Stop Us Now" is a song co-written by Albert Hammond and Diane Warren, recorded by Starship. Featured as the theme to the romantic comedy film Mannequin, it hit #1 in the Billboard Hot 100 on April 4, 1987 and reached #1 on the UK Singles Chart for four weeks the following month and became the UK's 2nd biggest selling single of 1987. At the time, it made Grace Slick the oldest female artist to have a number one single in the United States, though the record was later broken by Cher's "Believe" in 1999. The song also received an Oscar nomination for "Best Original Song" at the 60th Academy Awards. It was released on the album No Protectionin 1987.

In a radio interview, Albert Hammond said that the idea for the song came from his impending marriage to his live-in girlfriend of 7 years, after his divorce from his previous wife was finalized. He had said to Diane Warren, "It's almost like they've stopped me from marrying this woman for seven years, and they haven't succeeded. They're not gonna stop me doing it."
