Morvan was born in 1966 in Paris, France, to parents from Pointe-à-Pitre, Guadeloupe. At 18, he moved to Germany, where he was a dancer and model, and was influenced by funk, soul, hip hop and pop. He met Rob Pilatus in a nightclub in Munich, and they decided to form a rock/soul group.

The first Milli Vanilli album was Girl You Know It’s True. Despite critical derision, Milli Vanilli’s fame continued to grow worldwide. The album had four hit singles: the title track, and the group’s three #1 hits, “Girl I’m Gonna Miss You”, “Baby Don’t Forget My Number”, and “Blame It on the Rain”. Milli Vanilli won the Grammy Award for Best New Artist on 22 February 1990 for Girl You Know It’s True.

When Morvan and Pilatus pressured Farian to let them sing on the next album, Farian admitted to reporters on 15 November 1990 that Morvan and Pilatus had not actually sung on any of the records. As a result, Milli Vanilli’s Grammy was withdrawn four days later and Arista Records dropped the act from its roster and deleted their album and its masters from their catalog, thus making Girl You Know It’s True one of the largest-selling albums to ever be taken out of print. A court allowed any American who bought the album to get a refund.

In 1997, Morvan was interviewed for the premiere episode of VH-1’s Behind the Music. He was also featured in a 2000 BBC documentary on Milli Vanilli. Morvan then spent 2001 on tour, before performing in 2002 as the inaugural performer at the brand-new Velvet Lounge at the Hard Rock Café Hotel in Orlando, Florida.

Pilatus later served three months in jail for assault, vandalism, and attempted robbery. He spent six months on drug rehabilitation before returning to Germany. He died of an alcohol and prescription drug overdose at a hotel in Frankfurt on 2 April 1998.

Morvan spent several years as a session musician and public speaker. In 1998, he was hired as a radio DJ at famed L.A. radio station KIIS-FM. During this time, he also performed at the station’s sold-out 1999 Wango Tango festival concert before 50,000 people at Dodger Stadium.

In 2003, Morvan released his first solo album, Love Revolution, producing, recording, writing and singing all the tracks. On 14 April 2011, Morvan released a new single, “Anytime”, to digital outlets.

On 14 February 2007, it was announced that Universal Pictures was developing a film based on the true story of Milli Vanilli’s rise and fall in the music industry. Jeff Nathanson, a screenwriter from Catch Me If You Can, was to write and direct the film. Morvan was supposed to serve as a consultant, providing his and Pilatus’ point of view. However, the project was never completed. In 2011 German director Florian Gallenberger declared that he was reviving the project and would be rewriting the script.

On 26 March 2007, the Milli Vanilli Best of the Best album was released.

On 25 May 2012, Morvan released a single, “See the Light” with a new band, Fabulous Addiction.

In March 2014, it was mentioned that Morvan was working on his next single in Los Angeles with Grammy-winning producer Clarence Jey and Grammy-winning singer Delious Kennedy from U.S. R&B group All-4-One.
