Justin Bieber was just a baby when Friends premiered in 1994, but that doesn't stop him from using the name of one of the show's characters as an alias for when he's on the road touring, Matthew Perry tells Ellen Degeneres on Tuesday's Ellen.

Perry said he found out that when Bieber checks into a hotel, he checks in under the name of Perry's Friends character, “Chandler Bing.”

"Well now people know," Degeneres said.

Matthew Perry and Matt LeBlanc are more than just friends, thanks to a love triangle created by their new TV comedies. The girl in the middle?  Andrea Anders, RadarOnline.com has learned.

LeBlanc and Anders have been dating five years. They met when she was hired to play his girlfriend -- we're sensing a pattern here -- on his Friends spin-off series, Joey. LeBlanc was then married to Melissa McKnight.  They split after just three years, and he and Andrea then went public as a couple.
