Richard Simmons: Christmas Got All Grinchy ... No Love For Carolers (VIDEO)

Even Christmas carolers can't get Richard Simmons to come out of hiding.

It's like a page was ripped out of a Charles Dickens novel ... carolers serenaded Simmons at his Hollywood Hills home  ... to no avail.

Simmons hasn't been seen in almost 2 years, even cutting ties with some of his closest friends. His rep told us he's just enjoying life out of the public eye.
