The absolute worst time for a need for dental braces to arise is when you're due to have your yearbook photo taken, and so we feel for Jeremy Piven here. You can sense the awkwardness radiating from him - although part of that might come from his hairstyle, which doesn't appear to know what it's doing, or what it wants to be. Somehow, despite looking like this, he would play a college jock during his first major role in 'Lucas' during the 1980s.
Somewhere along the line, Piven clearly learned a thing or two about personal grooming. You won't see many men in Hollywood as well turned out as Piven always seems to be. His immaculate good looks (along with his acting talent) have won him a number of big roles in shows like 'Seinfeld,' but our younger readers probably know him better for the part of Ari Gold in 'Entourage,' for which he's been decorated with awards. When he's not acting, you'll sometimes find him playing drums for the band 'Bad Decisions,' of which he's made very few in his career.
