Jim Parsons has won the 2011 Emmy Award for Outstanding Lead Actor In A Comedy Series for his role as physicist Sheldon Cooper in "The Big Bang Theory," marking the actor's second win and third nomination for the same part since the CBS comedy series began in 2007.
Parsons beat co-star Johnny Galecki, who plays Leonard Hofstadter on the show, as well as other nominees Matt LeBlanc of "Episodes," Louis C.K. of "Louie," Alec Baldwin of "30 Rock" and Steve Carell.
Carrell lost his sixth and final chance to bring home an Emmy for his role as egotistical boss Michael Scott on "The Office."
Parsons, 38, had earned the same award in 2010, marking the show's first Emmy win.
The actor, who is from Texas, has an MFA in Acting from the University of San Diego and began his on-screen career less than a decade ago, appearing in an episode of the series "Ed" in 2002. He later landed a recurring role on the show "Judging Amy" in 2005 before starring in "The Big Bang Theory."
The fifth season of "The Big Bang Theory" is set to premiere on Thursday, September 22. CBS announced earlier this year that the show is set to continue to air until at least 2014.
"The Big Bang Theory" has been nominated for a total of 13 Emmy Awards and earned five nominations at this year's ceremony, including one for "Best Comedy Series." The show's leading female star, Kaley Cuoco, has never received an Emmy nod.
The 2011 Emmy Awards ceremony was held at L.A. Live's Nokia Theatre in Los Angeles on Sunday, September 18 and was hosted by "Glee" actress Jane Lynch. Check out a full list of nominees and winners.
