Martina Big

Martina Big (born 17 May 1988; baptised as Malaika Kubwa in 2018) is a German model and actress known for undergoing extensive body modification. In 2015, she became known for her extremely large breast implants. In May 2019, she replaced her previous breasts implants with new, even bigger expandable models, which are the biggest breast implants in the world with a rated volume of 20,000cc each. 
Life.
Big was born in a Western German town, "close to the border to Luxembourg", on 17 May 1988. After receiving a high school diploma, Martina (as she was then known) began her career as a flight attendant alongside her longtime partner Michael, who was a pilot. She stopped working as a flight attendant in 2012 to pursue modeling and acting full-time. 
On 3 December 2012, Martina underwent a breast augmentation with large expandable implants. Since then Martina had 23 procedures to add volume in her breasts, reaching a bra size of 32S.
In January 2017, Big had a medical treatment that turned her appearance into that of a black woman. In February 2018, she traveled to Nyeri, Kenya, where Pastor Isaac Murage of the Gichira Baptist Church baptized her, and, according to Big, declared her to be a "true African woman." She was given the baptismal name Malaika Kubwa; in Swahili, malaika means angel and kubwa means big.
In September 2017, Big confirmed on the Swedish television show "Outsiders", that she had the biggest breasts in Europe, employing a water displacement test.
