It appears that “Mad Men” star Jon Hamm’s private life may be in contention for public consumption with the iconic character he plays on cable television.

Fresh off completing in March a stint in rehab for alcohol addiction, Hamm, whose AMC series ends May 17 after an 8-year run, now faces scrutiny for participating in a reportedly violent hazing while as a student at the University of Texas in 1990, which led to criminal charges.

Criminal records obtained by the Associated Press show that Hamm, now 44, was charged with hazing and received probation. A separate charge of assault was dismissed. The University of Texas chapter of the Sigma Nu fraternity was permanently disbanded.

It was not immediately known how or why a subsequent 1991 lawsuit filed by a member of the fraternity re-surfaced. The Associated Press reported that the the Emmy-nominated actor and `Mad Men” creator Matthew Weiner did not respond to requests for comment.

In the 1991 lawsuit, the pledge, Mark Allen Sanders, said Hamm participated “till the very end.” According to the lawsuit, Hamm became “mad, I mean really mad” after Sanders, joining the fraternity, failed to recite things he was supposed to memorize about Hamm and other fraternity members.

Sanders said Hamm set his jeans on fire, shoved his face in dirt and hit him with a paddle.

Sanders said he needed medical care and withdrew from the school. Court records show that the lawsuit was dismissed in 1993. Sanders or his former attorney could not be reached for comment.
