Photos: Celebrity breakups we have never gotten over Once upon a time in 1999, a young blonde pop star named Jessica Simpson met another young blond-ish pop star, Nick Lachey, at a Teen People party, and they immediately fell in love. Lachey even wrote a song about their passion -- that would be "My Everything" -- and then he and his new bride signed up to film their love for an MTV reality show called "Newlyweds." But instead of finding "happily ever after," Lachey and Simpson found grounds for divorce in 2005 after three years of marriage. They both are now parents and married to others. Hide Caption 2 of 17

Photos: Celebrity breakups we have never gotten over In 2001, every teenager with access to MTV and Teen People wanted to find the Britney Spears to their Justin Timberlake (or vice versa). With those two ruling pop music, not even their questionable fashion sense could mar the public's love for their romance. Sadly, matching denim outfits wasn't enough to make this last: The couple broke up in 2002, and many listeners believe Timberlake's "Cry Me a River" is about his relationship with Spears. Spears had a super brief marriage to friend Jason Alexander in 2004 and was married to backup dancer Kevin Federline from 2004 to 2007. Timberlake married actress Jessica Biel in 2014.

Photos: Celebrity breakups we have never gotten over Madonna's four-year marriage to Sean Penn was one of the wildest rides of the '80s, and that's saying something, but we agree with her words after their divorce in 1989: "I do believe we all have soul mates," she told People magazine. "I don't believe that we necessarily end up with them." After their split, both Madonna and Penn moved on to new relationships (several times). Hide Caption 6 of 17

The pair met at a New Edition concert in 1985 and married in 1987, welcoming daughter Zoe a year later. "We were very young, and it was wonderful," Kravitz recalled in 2013.

Photos: Celebrity breakups we have never gotten over From their first screen test for 2008's "Twilight," Robert Pattinson and Kristen Stewart were the perfect match. According to director Catherine Hardwicke , Stewart "felt connected to (Pattinson) from the first moment. That electricity or love at first sight or whatever it is." Whatever "it" was, it didn't survive a cheating scandal in 2012, when Stewart admitted that she'd had a "momentary indiscretion" with her "Snow White and the Huntsman" director, Rupert Sanders. She went public with her relationship with screenwriter Dylan Meyer in 2019. Hide Caption 10 of 17
