These celebrity couples had a bad case of cold feet.
Drew Barrymore & Leland Hayward III
Drew Barrymore got engaged when she was only 16 years old! She called it quits with Hollywood producer Leland Hayward's grandson the same year she almost tied the knot.
Cameron Diaz & Jared Leto
These two famous Hollywood actors were engaged in 2000, but broke up three years later.
Julia Roberts & Kiefer Sutherland
After only one year of dating, Julia Roberts and her Flatliners co-star almost made it down the aisle. Roberts called the wedding off days before the ceremony, and Sutherland moved out of Robert's home on their planned wedding day.
Jennifer Lopez & Ben Affleck
You've probably seen these two in Jennifer Lopez's 2002 single Jenny from the Block. The couple, known as "Bennifer", called their wedding off in 2004.
Evan Rachel Wood & Marilyn Manson
Actress Evan Rachel Wood recalled her relationship with Manson as "free" rather than "rebellious." She started dating him when she was 19, but things didn't seem to work out after she got engaged in 2010.
Demi Moore & Emilio Estevez
The Breakfast Club actor and actress Demi Moore were engaged for a few years before they broke up.
Jill Schoelen & Brad Pitt
Academy Award winning actor Brad Pitt was engaged to actress Jill Schoelen before he got married to Angelina Jolie. He was engaged for three months in 1989, until Schoelen dumped him because she fell in love with a film director.
Kate Moss & Pete Doherty
The on-and-off relationship between supermodel Kate Moss and The Libertines frontman lasted from 2005 until 2007.
Sheryl Crow & Lance Armstrong
Is it possible that this relationship didn't work out because of Armstrong's doping case in 2006? The cyclist said he wasn't keen on having kids, but Crow wanted children, so that's why they called it quits. They ended their relationship in 2006, after getting engaged 5 months earlier.
Sandra Bullock & Tate Donovan
These two started dating in 1992 and eventually got engaged, but their love didn't last, so they split three years later. Bullock later told People: "My priorities were him first, me second."
