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.

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