Sean Mandell: LA entertainment correspondent on the tributes flooding in for 'Friends' star Matthew Perry - Heather du Plessis-Allan Drive

Friends cast-mates haven't yet spoken publicly about the death of Matthew Perry, known to millions as Chandler Bing.

The 54 year old was found dead yesterday in the hot tub at his LA home.

LA entertainment correspondent Sean Mandell says the only reactions reported so far come from sources close to Lisa Kudrow.

"Sources close to Kudrow have expressed that Kudrow is allegedly confused and baffled, believing that Perry was in good health recently, that certainly he had been sober."
