With the complex relationship history Emma Roberts and Evan Peters have had, a photo of these two should be next to a dictionary definition of "on again, off again." After two broken

engagements, it looks like these two are back on. Third time's a charm, right? 

The diva and the billionaire split in 2016 after rumors of cheating began whirling. Knowing Mimi, though, she probably hardly even remembers his name anymore.

The American Pie costars broke off their engagement in 2005, ending a five-year relationship. Holmes moved on (and then off) to form one-half of the infamous TomKat, while

Dating for less than one year didn't stop these crazy kids from getting engaged in 1986. The Wisdom costars then went their separate ways but continued to work together. Estevez

even directed Moore in 2006's Bobby. 

Even though the Edward Scissorhands costars' engagement was called off doesn't mean they're not together in one very permanent way; Johnny has "Winona Forever" tattooed on his arm.

Cameron Diaz and Jared Leto dated from 1999 to 2003 and were engaged for three years. Their marriage plans never panned out, but Diaz made quite the impression on her almost-mother-in-law.

Constance, Leto's mother, attended Diaz's 2015 marriage to Benji Madden.

An eighteen year age difference and a ton of backlash didn't stop Evan Rachel Wood and Marilyn Manson from dating for four years, and then getting engaged in 2010. They

broke it off by 2011, but the two remain amicable. "I appreciate everything he taught me," Wood has said. "I just don’t think we were right for each other."

The original Bennifer, remembered for such High Art films as Gigli and Jersey Girl, had a whirlwind two year relationship between 2002 and 2004, when Affleck called off their

impending wedding. 

These two Canadian cuties met at a party thrown by Drew Barrymore in 2002, kicking off their five-year relationship. They called off an engagement in 2007, and as far

as we know, Morissette did not enshrine the relationship in a song like certain other relationships she had.

Hey again, Johnny. He was also engaged to Dirty Dancing star Jennifer for a hot second in 1989. The couple called it off after a year.

The cyclist and singer were engaged for five months in 2006, but their differing family goals brought their relationship to its end. “She wanted marriage, she wanted children; and not

that I didn’t want that, but I didn’t want that at that time because I had just gotten out of a marriage, I’d just had kids,” Armstrong wrote in

his memoir, Lance. “Yet we’re up against her biological clock — that pressure is what cracked it.”

These two were engaged in 2004, and it all came crashing down after the highly-publicized affair that Jude Law had with their childrens' nanny. They then reunited years later

in 2009, and decided they were right the first time in 2011, when they split again.

Tara Reid and Carson Daly met in the most early-aughts way ever: on the set of Total Request Live. After one year of dating, between 2000-2001, they called

off their wedding plans. "To some extent, I dodged a bullet. I was getting serious about my career, and she wanted to shoot movies and just party in her time

off. That didn't work for me," Daly told Elle. Um...harsh. We're pretty sure she's better off.
