Oldest Woman in the World Misao Okawa -- 116th Birthday ... And Zero Plastic Surgery

She's 116 years old today -- and she still looks better than half of Hollywood.

Misao Okawa -- recognized by the Guinness World Records as the world's oldest woman -- celebrated her record-breaking birthday today at a nursing home in Osaka, Japan.

She officially became the world's oldest person back in 2013 -- you know, after the last one died.
