3. Jennifer Lopez and Ben Affleck
In 2002, the media worked itself into a frenzy over “Bennifer” (Ben Affleck and Jennifer). They had a hit music video together called Jenny from the Block and a movie that completely bombed: Gigli. They were in love and were set to marry in September 2003. Ben even got Jennifer a $1.2 million ring with a pink diamond. Shortly before the wedding, though, word got out that Ben cheated on Jennifer with a stripper. Jennifer said in interviews that she was heartbroken, and called it off.
