Hanson Perform 'MMMBop' On 'Dancing With The Stars'

Hanson took over 'Dancing With The Stars' dance floor with their oldie 'MMMBop.' Watch it here!

These brothers haven't quit music, in fact they're still quite active but nothing has reached the fame of their hit 'MMMBop.' So they had no problem in performing it on the hit TV show while the experts dance around to the feel-good tune.

One thing is for certain, the guys are all grown up and looking great. It seems a bit ridiculous for them to be on TV in 2011 but we couldn't help but smile and feel a bit nostalgic for when they were just boys taking over the airwaves in the '90s. Will Justin Bieber fans feel this way when he croons 'Baby' in 10 years?

What do you think of their performance of 'MMMBop'?
