Back in 1998, "That '70s Show" was a new hit show, and Wilmer's star was definitely on the rise thanks to the ratings and his lovable and laughable take on Fez. Offscreen, though, Wilmer was just starting to work his way through a bevy of famous beauties. First on his list was a rising songbird named Christina Milian. By most accounts, the two dated briefly in the spring of 1998 but broke up shortly thereafter. However, it wouldn't be the end of their relationship: Wilmer and Christina have remained friends for years and dodged rumors from time to time that they were rekindling a youthful love affair.
