The film was slated by critics and shunned by cinemagoers when it was released in 2003, causing it to flop badly - much like Affleck and Lopez's real-life romance.
It was pulled from theatres after just three weeks, earned its stars Razzie Awards and now comes out top in Moviefone.com's new list of of the worst.
Editors picked Gigli above Paris Hilton's movie flop The Hottie & the Nottie; American Idol spin-off From Justin to Kelly and Ellen DeGeneres' Mr Wrong.

1) Gigi, 2003
2) The Hottie & the Nottie, 2008
