Charlie Sheen -- I'm Gonna See My Sons for Christmas!

EXCLUSIVE

Charlie Sheen is no longer on Santa's naughty list ... the actor was just given an awesome Christmas gift -- permission to celebrate with his twin boys.

Sources close to the situation tell TMZ ... the kids temp guardian Scott Mueller (Brooke Mueller's brother) has no interest in punishing Bob and Max on Christmas ... so he and Sheen hooked it up.

We're told Charlie's stoked that he can spend Christmas with the boys -- it takes the sting not seeing daughters Lola and Sam ... who are going on a trip with other ex-wife Denise Richards ... Sheen claims he's not allowed to tag along .

Bah humbug.
