Ashton wasn't too busy pulling wacky pranks on "Punk'd" to meet the love of his life. (Yes, we all know how this turns out, so let's just pretend for a minute that all Hollywood marriages last forever.) He and Demi started dating in 2003, and when they decided to tie the knot, they naturally did it at the Kabbalah Centre. He was 27, and she was 42, and we pinned all our hopes and dreams on their love. They would blaze a trail for other celebs by revealing every sweet, romantic, cooing moment on Twitter, reminding us that their love was a perfect and eternal union without blemish or flaw. Also, by 2009, @AshtonKutcher would be the first Twitter handle with a million followers.
