Johnson has yet to publicly acknowledge their relationship, but she has alluded to being taken in magazine interviews, saying "I have a boyfriend that I’ve been with for a while." According to her beau's IMDB profile, his big break seems to be a role in The 40-Year-Old Virgin, and has since played a turn in everything from Greek to Last Man Standing.
On a more controversial note, he's also rumored to be a very active member of The Church of Scientology — along with the rest of his family, who reportedly have high roles within the church. Masterson has yet to speak out about this thoughts on his girlfriend's latest film project — or whether he's a fan of Fifty Shades — but we're sure to see more of him in the near future. (IBT)
