Criminal Minds: Matthew Gray Gubler, Dr. Spencer Reid on Criminal Minds, wants to do a "Alvin and the Chipmunks" sequel.
"If Justin Long, who voiced Alvin, or Matthew Gray Gubler (Simon) have anything to say about that, I imagine the sequel won't be a family movie -- both commented on their hotness and anatomy. Whatever happens, I'm sure you can expect some strategically-placed clothing, but either way, the Chipmunks are here to stay -- at least for a few more rounds of money making. What say you? Would you like a CG-dose of Chipettes?"
