7. Tara Reid and Zack Kehayov
Tara Reid's engagement announcement on Twitter was shocking enough, then we were blown away when that tweet was followed up by word that they'd married just hours later! She and Deloitte consultant Zack Kehayov were vacationing in Greece in August 2011 when they decided to say "I do." It's unclear exactly how long those two had been dating, but sources say it's been a matter of months. The actress denied that the marriage was legal weeks later.
