Zac Efron and Vanessa Hudgens

Arguably the cutest teeny bopper couple of the early 2000s, these High School Musical co-stars definitely gave us #RelationshipGoals! Unfortunately, the Disney couple called it quits in 2010. Recently, Vanessa opened up about the public breakup to the New York Times and cited her jealousy as the root of their split. "I went through a phase when I was really mean because I was so fed up. Girls were running after him, and I was giving them death stares. Then I realized that's not what that's about," she said.

Kim Kardashian and Reggie Bush

Before Kim and Kanye there was the Bush and the Tush! Back in the early days of Keeping Up With the Kardashians, these two were too cute for words, but in 2009, after two years together, they ended things. Though they decided to break up, it was never reported that there was bad blood between them. According to People, the long-distance relationship didn’t work out because they spent too little time together. “They never get to see each other, ever,” the source said. “They still love each other and are part of their lives, but Reggie spends six months out of the year in New Orleans, so it’s tough.”

Jessica Simpson and Nick Lachey

From 2002 until 2006 Nick and Jessica were the couple to be! The Newlyweds: Nick and Jessica stars gave fans an inside look at their seemingly perfect marriage. But sadly, the couple ended their relationship. In a joint statement the duo said, “This is the mutual decision of two people with an enormous amount of respect and admiration for each other.” Though the statement alleges that the split was mutual, some have said that Jessica was fed up with Nick’s partying.

Khloé Kardashian and Lamar Odom

KoKo and Lam Lam were truly one of reality TV’s best couples. The duo wed in 2009 and quickly stole America’s hearts when they starred in Khloé & Lamar. But sadly, the basketball star’s addiction and infidelity tore the marriage apart and the duo finalized their divorce last year. The Revenge Body star recently celebrated a big step in moving on from her former beau by changing her name and removing the “Odom”.

Justin Bieber and Selena Gomez

This classic romance blossomed in 2010 and the duo quickly became a fan favorite as Justin’s music career was beginning to sky rocket. But in 2011 a fan accused Justin of fathering her child and Jelena’s relationship went quickly downhill. And just this past summer, Sel was seen throwing shade at her former beau when she commented on the “Sorry” singer’s Instagram post. “Funny how the ones that cheated multiple times are pointing the finger at the ones that were forgiving and supportive, no wonder fans are mad,” she wrote on a snap of the Biebs with his ex Sofia Richie.

Robert Pattinson and Kristen Stewart

These Twilight co-stars stole the hearts of young teens everywhere! But sadly in 2012, the young couple disappointed their fans big time when they went their separate ways. The split came as a result of Kristen’s infidelity after she was caught cheating with director Rupert Sanders. K Stew issued a public apology for her indiscretions stating, “I love him, I love him, I’m so sorry.”

Justin Timberlake and Britney Spears

When Justin and Britney parted ways, the every teen’s heart skipped a beat. After cheating allegations arose against “Oops! I Did It Again” songstress, Justin was quick to end things. Even though this breakup totally rocked our world, it did still bring up “Cry Me A River” and, come on, that’s really a classic.
