ARNOLD SCHWARZENEGGER: Hollywood actor Arnold Schwarzenegger, whose marriage recently ended over an extramarital affair, has signed on for a role in a western, EW.com said.
The 63-year-old former Republican California governor is to play a small-town border sheriff battling a Mexican drug cartel in "The Last Stand," which is to begin shooting in September, the entertainment news Web site said.
The film, which is set for a 2012 release, will mark the English-language debut of Korean director Jee-woon Kim, EW.com reported.
The Austria-born Schwarzenegger is a former body builder best known for his work in the string of "Terminator" movies, as well as in "Total Recall," "True Lies" and "Twins."
His wife Maria Shriver recently filed for divorce from him after she discovered he fathered a child during their marriage more than a decade ago with a domestic servant. He and Shriver have four children together.
COREY 'BIGHOSS' HARRISON: Corey "Big Hoss" Harrison, a cast member of the Las Vegas-set reality show "Pawn Stars," says he has lost about 115 pounds during the past year.
The History (formerly known as The History Channel) series follows three generations of a family that owns a pawn shop and deals in rare and fascinating items.
"I was watching this lawyer's commercial and it was talking about the side effects of this drug and I was on that medication because of my weight," Harrison told People.com. "I went and got a Lap-Band put in and the weight just started falling off. It was like someone took a backpack full of rocks off of you."
Thanks to the Lap-Band, a protein-heavy diet and workouts with a trainer five days a week, Harrison told People.com he is now off of the medication and weighs in at about 250 pounds.
