Celebrities might seem like they have it all – a successful career, beautiful looks and a significant other who everyone runs after.  Though their lives may appear perfect, don’t be fooled by the glitz and glamour of Hollywood’s shine.  We all know that some romances don’t last, and the following pairs are no exception.  Here are five celebrities who were bitten by the cheating bug – and then burned by their former flame:

1. Britney Spears and Justin Timberlake: Timberlake admitted to falling in love with Spears when they first met on the set of The Mickey Mouse Club in 1993.  “I was infatuated with her from the moment I saw her,” he told CBS News.  The couple started dating five years later, but ended their relationship in 2002 when Spears allegedly cheated on Timberlake with choreographer Wade Robson.  Shortly after their split, Timberlake released ‘Cry Me A River,’ a revenge song for Spears.  However, the N’Sync singer later told MTV, “The song is not about her.  The video is about me.”

2. Meg Ryan and Dennis Quaid: This actor pair divorced after she was caught cheating with Russell Crowe while filming Proof of Life in 2000.  She used Quaid’s infidelity to explain her own actions and accused him of adultery throughout their marriage.  Quaid fought back and said, “It was eight years ago, and I find it unbelievable that Meg continues publicly to rehash and rewrite the story of our relationship.”  Although Quaid and Crowe both have new loves in their lives, the You’ve Got Mail star remains single.

3. Valerie Bertinelli and Eddie Van Halen: Bertinelli revealed to Oprah Winfrey in 2008 that she and her ex-husband cheated on each other.  “He claims to this day that I cheated first, but I don’t know,” she said.  “I don’t know about the timing.”  Although their 25-year marriage ended in 2006, they remain friends.  Bertinelli even attended Van Halen’s wedding to Janie Liszewski in 2009.

4. Elizabeth Edwards and John Edwards: When John Edwards admitted to having an affair, his wife Elizabeth Edwards got the ultimate revenge.  In her will, which was released on January 2011, she left all of her possessions to her children.  Well, can you really blame her?  After all, who bothers leaving something to their cheating spouse?

5. LeAnn Rimes and Eddie Cibrian: This couple is a double whammy.  Rimes not only ruined her own marriage, but also Cibrian’s, as the couple cheated on their spouses with each other while filming Northern Lights.  They eventually tied the knot this year, despite rumors about Cibrian cheating on Rimes with his estranged wife.  The saying “once a cheater, always a cheater” comes to mind in this situation.
