Julia Roberts and Kiefer Sutherland It was supposed to be the wedding of the decade in 1991 when Julia Roberts and Kiefer Sutherland - two of the biggest up-and-comers of the time - were set to tie the knot. But just days before the wedding they parted ways. On the day that the wedding was supposed to be taking place, June 14, 1991, Kiefer was seen moving out of her Hollywood pad. Rumors of infidelity swirled, but years later, the "24" star explained:“There was a huge connection between us but…it was more like friends than the passionate relationship that she or I would have wanted. She saw that; I did not.” (Reuters)

Jennifer Lopez and Ben Affleck "Bennifer" broke up several times before officially calling it quits in Jan. 2004. As you may recall, they had an elaborate wedding all planned for Sept. 2003 and then "postponed" it supposedly due to too much media attention.

"It's the start of a new day, and a new week, and I'm happy to be single," he recently Tweeted. (AP)

Kat Von D and Jesse James When Jesse moved on from Sandra Bullock with Kat Von D, they seemed like an ideal pair. They were instantly engaged, but now just six months later, they've announced there will be no wedding. A scorned Kat broke the news on her Twitter page: "I am no longer with Jesse and out of respect for him, his family and myself, that's all the info I'd like to share," she wrote. "Thanks for respecting that." Jesse on the other hand gave People magazine a reason for the demise. "The distance between us was just too much," he said.
