Day26 and Qwanell
Day26 is a boy band created by the show Making the Band. The show wanted to celebrate the talents of up-and-coming artists to create an R&B boy band. Apparently, member Qwanell was a huge trouble maker and constantly picked fights with his band members and managers. This ended up creating tension on an otherwise popular group which led them to their downfall.
Tom Cruise and Rob Lowe
The Outsiders is one of the most iconic films to come out of the 1980s. Tom Cruise and Rob Lowe were new in their careers. The would-be superstars ended up getting along poorly enough where Lowe punched Cruise in the face. They continued filming but weren't happy about it.
