15Danny Moder and Julia Roberts
Even though Danny Moder was a mere cameraman before he somehow snagged the attention of Julia Roberts, her celebrity presence all by herself is enough to land him on this list. Moder was married while he was working on the set of her film The Mexican. Interestingly enough,
Roberts was also in a relationship at the time with actor Benjamin Bratt. They started dating and once Moder's divorce was finalized, they became married shortly after. They have three children together and have been married since 2002. Despite the fact that both of them were involved with other people when they met, they seem to be making it work. At least, in the Hollywood sense, as their union has lasted significantly longer than most celebrity marriages seem to.
