Martina Big, 28, was seen standing in front of the Hollywood hills in Los Angeles showing off her £50,000 figure.
The German glamour model since vowed to make her skin “darker and darker and see what the limits are”.
While standing in front of the iconic Hollywood sign, Martina said: “Last time I visited this with blonde hair and white skin.”
The ex-air hostess added: “And now I’m a black woman with African hair.”
Her video has already been watched more than 137,000 times and has completely divided viewers.
One wrote: “I’m not pleased or supporting this mess. I’m a black woman as you can see and I don’t think this is cool. It’s sad. It’s pitiful. I think she may have mental issues.”
