A British-born wannabe hip-hop star, Claudia Aderotimi has died after an illegal cosmetic procedure to enhance her buttocks went tragically wrong.The 20-year-old London-born who is believed to be half Ghanaian and half Nigerian, also called Claudia Adusei and Claudia James, died of heart attack after flying to Philadelphia, USA for the operation, which would give her a larger and shapelier bottom from silicone jabs to increase the size and curve of her buttocks.A resident of Hackney, East London, Claudia suffered chest pains after the injections and died in hospital. US cops are investigating the matter.Claudia was desperate to transform her image with cosmetic surgery so she could appear in music videos.The 'operation' took place at a low-cost hotel in Philadelphia, where she was injected with industrial silicone (which is normally used as a sealant in buildings), rather than the medical grade silicone used in enhancement surgeries.Doctors believe this triggered chest pains and a heart attack that led to her death because it was accidentally injected directly into a vein.A preliminary examination found the silicone filler had leaked into her bloodstream, leading to heart failure.Ms Adusei had travelled with three of her friends, one of whom was supposed to have a hip enhancement surgery using the same technique to make her hips look juicier.According to British news reports, Ms Adusei had a similar procedure in the hotel last November and was returning for a "top-up" injection. The female 'surgeon' who performed the procedure disappeared after the victim began complaining of chest pains.She was rushed to a hospital in Philadelphia, where she unfortunately died.Friends revealed her confidence had dipped after she was dropped from a previous promo because her buttocks, were too flat.But the $2,000 procedure, carried out in a $100-a-night Philadelphia hotel, ended in disaster when Claudia suffered agonising chest pains and died.Talent scout, Tee Ali, who met the university student when she filmed a video, told The Sun: "She was a dancer and choreographer."The problem was she didn't have no butt, and she wanted a butt."She went to audition for one video shoot wearing fake booty pants and she got all the attention."But when they found out it was fake she didn't get asked back."He described her as 'a victim' of social pressure to be perfect and thought a larger bottom would make her famous.The Thames Valley University student developed chest pains and struggled for breath 12 hours after she had the illegal silicone injections at a budget hotel.Police said she and her pals checked into the cheap Philadelphia hotel to have the illegal procedure.But almost 12 hours after receiving the injections in her rear she began complaining of chest pains and was rushed to hospital, where she died at 1.32am on Tuesday.Toomi said: "She said she was going to the US but didn't say why - we thought it was a holiday."The hotel manager Jason Britton said staff had no idea ops (operation) were being performed there. He said: "We're co-operating with the authorities."One of the UK's top plastic surgeons said Claudia's procedure was illegal and like "Russian roulette".Source: Daily Guide
