In The Real Housewives of Beverly Hills, the husbands are almost as popular as the main cast. The women are the stars of the show, but sometimes it's entertaining seeing a man's point of view on some of the ladies' issues. More than that, viewers love seeing all aspects of the main casts members' lives, and their husbands are a big part of that.

While the husbands' involvement changes by season, there's usually a funny one-liner thrown in by one of the guys. They join the ladies on group dinner dates, they go on vacations together, and they even make appearances in confessionals and reunions.
