The Backstreet Boys are finally "larger than life!"

A.J. McLean, Howie Dorough, Kevin Richardson, Nick Carter and Brian Littrell received a star on the Hollywood Walk of Fame on Monday!

BSB just embarked on another international tour to celebrate 20 years of being together, and they've aged pretty well. Youngest member Nick, now 33, is still a babe. And A.J. is sporting a brand new head of hair, thanks to a recent hair transplant, not to mention painted nails.

Some of the Boys took to Twitter to express their excitement:

"Received a star on the Hollywood Walk Of Fame today with My BSB Brothers. One of the happiest days of my life. Thanks to all our fans today!" - @howied

"Huge day. Receiving a star on Hollywood blvd. WOW! Thank you to all our fans. #BSBWalkOfFame" - @nickcarter

"In Stone!!!! Thank GOD" - @brian_littrell (followed by an Instagram picture of him posing with the star)
