Charlie Sheen's representative has denied a new claim that the actor is being urged by family members to go to rehab for alcohol abuse.

"He is not going to rehab," the rep told UsMagazine.com, adding, "Who told him to go to rehab? Correct answer: no one."

This follows Tuesday's rehab reports regarding Sheen's wife, Brooke Mueller Sheen.

Published reports had said that Mueller had checked into rehab last week for alleged crack-cocaine abuse. Reps for Mueller could not be reached for comment by UsMagazine.com.

Sheen was formally charged Feb. 8 for assaulting his wife in a Dec. 25 incident. He allegedly put a knife to her throat and threatened to kill her while the two were vacationing in Aspen, Colo. He could face up to 3 years if convicted.
