SHANIA TWAIN: 7 MONTHS
When her best friend had an affair with Twain's husband, the singer broke her silence to PEOPLE about the end of her 14-year marriage to producer Mutt Lange in May 2008. Seven months later, a twist of fate would help the country star find love again with Frédéric Thiébaud, the ex-husband of the friend who betrayed her. Proving their love was more than a rebound romance, the couple married on New Year's Day 2011. "Fred has given me a new lease on love," Twain told PEOPLE.
