After realizing he wasn't 'beautiful' at age 17 when he went to an acting class, the Brazilian started getting plastic surgery, starting with a nose job and eventually having injections of polymethylmethacrylate, a filler.
Mauricio isn't the first to earn the title, either. Before he earned fame, another young Brazilian man named Celso Santebañes gained notoriety for spending roughly $47,000 on surgery to look like Barbie's mate.
Celso and Mauricio even had a public feud when Celso believed that Mauricio was trying to elbow his way into the Human Ken Doll market.
After Mauricio declared that he was the 'real' Human Ken Doll, Celso called him an opportunist and compared him to Michael Jackson, insinuating that Mauricio's plastic surgery looked unnatural.
The pair later came to an understanding before Celso passed away from leukemia at the age of 21 earlier this month.
