Comedian Kathy Griffin is the latest celebrity to be caught in paparazzi photos without makeup, joining the ranks of Snooki, Kim Kardashian and others who were seen without their Hollywood war paint. But the widely circulated photograph has been graded an “F” for the “My Life on the D-List” star, labeled as “unrecognizable” by many media outlets.

Griffin, 51, was hiking in Runyon Canyon in Hollywood on Wednesday with her 33-year-old boyfriend, Randy Bick, when the photos were snapped. The 51-year-old is seen wearing no makeup, with her hair tied in a topknot and a “Jimmy Kimmel Live” t-shirt.

Many media outlets including the Huffington Post and the Christian Post called Griffin “unrecognizable” after the images made their way on the Internet.

The au naturale photos bolster past comments maintained by Griffin that she hadn’t gone  under the knife nor has any cosmetic procedures under her belt.

"I SWEAR I haven't had anything in YEARS! Promise.No Botox, fillers NUTHIN!" Griffin posted on Twitter in June.

Photos of celebrities without makeup or Photoshop have become popular lately, after some supermodels including Gisele Bundchen, Heidi Klum, Adriana Lima and Alessanda Ambrosio were seen in unedited images sans makeup. The photos, which were the casting photos for Louis Vuitton's Fall 2010 runway show, virally circulated around the net after being posted on Reddit.
