Seven-time Emmy Award winner Betty White and her posse of senior pranksters are back for season two of "Betty White's Off Their Rockers," with an all-star line-up of guest stars helping to deliver big laughs when the NBC series returns on Tuesday, January 8 with two new back-to-back episodes at 8:00 and 8:30 p.m. ET.

Joining White for comedy bits in the new season will be Psy, Howie Mandel, Nicole Richie, Kim Kardashian, Steve O, Nick Lachey, NeNe Leakes, Ed Asner and Nick Cannon. Also appearing in entertaining skits with Betty will be "Real Housewives of Beverly Hills" Adrienne Maloof, Camille Grammer and Kyle Richards, along with Bob Harper.

White earned an Emmy nomination as Outstanding Host for a Reality or Reality-Competition Program in Season 1 of the NBC series. Now she's back for more laughs, and her fearless band of senior citizens continues their mission to execute cleverly crafted pranks, resulting in priceless reactions captured by hidden camera. This season, they'll head to New York City, Los Angeles, San Francisco, Seattle and Washington, D.C. looking for younger, unsuspecting marks. In iconic locations ranging from New York City's Central Park to San Francisco's Fisherman's Wharf to Washington, D.C.'s Capitol Hill and Georgetown, no one will be safe from their outrageously funny pranks.

Turning 91 years old in January 2013, White remains one of the busiest – and funniest – actresses in Hollywood, whose credits range from the classic "The Mary Tyler Moore Show" and "Golden Girls" to her current starring role on "Hot in Cleveland." With a career that has spanned more than 60 years, White has created unforgettable roles in television and film, authored seven books and won numerous awards, including those for her lifelong work for animal welfare.

"Betty White's Off Their Rockers" is adapted from the hit Belgium series "Benidorm Bastards." The international version of the series has been sold to more than 20 countries and has received many awards worldwide. "Benidorm Bastards" won the 2011 International Emmy Award for Best Comedy Series and swept the Rose d'Or Awards, winning the Best Comedy Award as well as the Golden Rose for Best Program of the entire competition. In addition, the show won Best Comedy Format at the 2010 FRAPA Format Awards.

Chris Coelen, Emma Conway, Matilda Zoltowski, Betty White and Tim Van Aelst are the executive producers of the series, produced by Kinetic Content.
