17. Jerry O’Connell
Jeremiah O’Connell has reached his 40s without anybody noticing at all. We’d have put him closer to 30, without a doubt.
The hubby of the gorgeous Rebecca Romijn (ex Stamos, by the way), made his debut when he was still a kid in the 1986 classic Stand By Me. He made a bunch of movies after that one but his more prominent roles were those in TV shows like Sliders, Crossing Jordan, Carpoolers and The Defenders.
O’Connell is a charming, good looking man and no one would give him a day over 30. Okay, maybe 35. But definitely not 41. He is also quite a funny guy, with a good sense of humor, which shows in his roles too. This might be one of the reasons he appears younger than he really is – funny people are always perceived as young at heart, energetic and vibrant.
