Christie Brinkley and Billy Joel
We were all rooting for this iconic 1980's couple, but they sadly called it quits in 1994, after 9 years of marriage. Looks like the Sports Illustrated Swimsuit model wasn't Billy Joel's "Uptown Girl" in the end. In fact, he wrote the song for his other ex-girlfriend, Elle Macpherson, so the rockstar must clearly have a thing for models.
