"Nothing's Gonna Stop Us Now" is a song co-written by Albert Hammond and Diane Warren, recorded by the American rock band Starship in 1986.
It is a duet featuring Starship vocalists Grace Slick and Mickey Thomas. Featured as the theme to the romantic comedy film Mannequin, it hit No. 1 in the Billboard Hot 100 on April 4, 1987 and reached No. 1 on the UK Singles Chart for four weeks the following month and became the UK's second-biggest-selling single of 1987.
The song also reached the top 10 in six European countries. The single became the first number one single by songwriter Diane Warren. At the time, it made Grace Slick (47 years old at the time of release) the oldest woman to have a number-one single in the United States though the record was later broken by Cher's "Believe" in 1999 (52 years old at the time of release).
The power ballad also received an Academy Award nomination for "Best Original Song" at the 60th Academy
Awards. In addition to appearing on the Mannequin soundtrack, the song was also released on Starship's album No Protection in July 1987.
The music video was released in late 1986 to promote Mannequin.
In a radio interview, Albert Hammond said that the idea for the song came from his impending marriage to his live-in girlfriend of seven 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."
The song has been considered "feel good" propelled by a strong synthesizer beat.
