Happy Birthday, Clay Aiken!

Before Adam Lambert, there was Clay Aiken.

Both artists rose to fame on American Idol; both finished second to artists that are unlikely to have more successful careers than these runner-ups; and both are gay.

The latter item is utterly irrelevant, but it does give Lambert and Aiken even more in common. That, however, is where the comparisons ends.

While the former superstar flaunts his sexuality and is known for flamboyant, controversial performances, the latter has quietly carved out a productive career for himself on Broadway and on the sales charts.

Aiken turns 31 today.
