A German air hostess turned glamour model has spent £50,000 on surgery in a bid to transform herself into an 'exotic Barbie'.

Martina Big, who says she is 28 and a size 6, has boosted her breasts to a size 32S, and uses tanning injections and her own powerful 50-tube sunbed to achieve her 'dark, crispy brown' complexion.

Martina, who claims to have the biggest breasts in Europe, has unique implants that can be further 'pumped up' by injecting saline - and she says she plans to spend more on surgery despite her already extreme looks.

The tanning addict once aspired to look like Pamela Anderson or Katie Price but has since decided they're 'not curvy enough', and says she wants to 'get darker and darker and see what the limits are'.

Martina first began dabbling with surgery in 2012, when her boyfriend encouraged her to take up modelling.

Nine weeks ago Martina had three melanin boosting injections that have turned her a deep shade of mahogany.

'I was not expecting to go so dark but it worked so well,' she said.

'I love it and I really want to push it to the extreme. Now I just want to get darker and darker and see what the limits are.

'I love the contrast of my bright blonde hair and my dark, crispy brown skin.

'I love seeing the reactions of people. I can see their big eyes when I walk past and their shocked faces, thinking "how is this possible?"'

Martina insists she is 'not pretending to be a black girl', but rather seeking to create a 'unique and exotic Barbie'.

'Yes, I have the skin of an African girl,' she said.

'But I am not pretending to be a black girl. I'm going to create a unique and exotic Barbie with dark tan, bright blonde hair and exaggerated curves. I like this look.'

She has no plans to curb her tanning addiction either - Martina says that she wants even more of the melanin increasing injections, and admits that she still uses a 50-tube sunbed installed at her home in Trier, Germany.

Martina claims that her fans were shocked when they saw her new look but they now like it and encourage her to 'go darker'

'At first, my fans were irritated saying "why did you do this?!" but that is because they have never seen a white girl change her skin to African dark before.

'But now, they have got used to it, they are excited like me. They say, "oh, I like your style! Go darker! Go darker!'''

Martina says that she is not trying to change her race and describes the extreme tan as just a part of her quest to become the 'ultimate real-life Barbie bimbo'.'

She says she will not change the colour of her eyes or eyebrows, which she says are 'the only natural things she will keep'.

Friends of Martina have been surprised by her decision and she admits even the doctor that administered the injections - whom she will not name - did not recognise her.

'In the seventh week after the injections, I went back to see my doctor. I said "hello", and he looked at me like "huh, who is this in my waiting room?"

'It was very funny.'

'He said: "I have never seen a girl turn so African dark before. Are you sure that you want this?" I told him "Yes!"'

'I love my skin like this. I love the extreme look.'

Martina says she 'loves her extreme look' and wants to modify it even more - she's planning a butt-lift later this year

The former air hostess began modifying her body in 2012 after her boyfriend, Michael, encouraged her to start modelling.

Initially, she had planned to have surgeries to enhance her bust and lips, but she soon found herself addicted to changing her body in increasingly extreme ways.

'At first, I wanted to look like Pamela Anderson or Katie Price. But now, I realise that is not for me. These women are not curvy enough.

'And so now, I am more inspired by Barbie or Jessica Rabbit, but I go my own way and am creating my own extreme look.'

Martina plans to have a butt-lift later this year, and will continue with her tanning.

Her boyfriend Michael is supportive, and he even had a course of tanning injections himself.

He said: 'I didn't want to go quite as dark as Martina but I support her and like her new look very much.

'It is a great feeling for me to have Martina by my side. I am the boyfriend of the woman with the largest breasts in Europe.

'I hope for the future that Martina will continue inflating her breasts, inflating her lips, getting more tanned and getting big butt implants.

'Martina has this extreme look because she has always followed her heart. She and I, our dreams are the same and from change to change, Martina just becomes even more beautiful.'
