Today on 'The Ellen DeGeneres Show' (weekdays, syndicated), Matthew Perry of 'Mr Sunshine' reveals that, in order to remain incognito, teen phenom Justin Bieber uses the name of his character from 'Friends' as an alias.

Perry seems all too eager to expose Bieber's secret, in fact. "I found out that he, when he checks into a hotel -- you know, we all use fake names -- he uses 'Chandler Bing,'" he said.

"Well, now people know," Ellen DeGeneres pointed out.

"I know. You've got to find a new one, pal," laughed Perry.
