Mark Harmon and Pam Dawber – Together for 34 Years

Mark Harmon and Pam Dawber are probably one of Hollywood’s longest-lasting couples. The couple exchanged the vows in 1987 and have been inseparable since. This is extremely impressive when you consider how soon relationships crumble in this era.

Mark and Pam have been blessed with two sons, one of whom has portrayed a young Gibbs on several episodes of ‘NCIS.’ This means it’s only a matter of time before the young one takes over for his old man. Unfortunately, despite the couple being relatively famous, they rarely make any public appearances, and no one knows what goes on in their lives apart from close friends and relatives.
