21 May 2010There has long been speculation that Nicole Kidman had a 'mummy makeover' following the birth of her daughter Sunday Rose in 2008, and a recent red carpet appearance has sparked new rumours that the star may have had a boob job.According to Mail Online, the 42-year-old actress wasn't shy about revealing her noticeably boosted assets as she wore a plunging dress to A Night With The Stars, a charity event helping to raise much-needed funds for the United Nations Development Fund for Women. This is not the first time Nicole has been in the spotlight for rumoured cosmetic surgery, after an event in October caused many to speculate that her wrinkle-free skin was a result of Botox treatments or dermal fillers. Make Me Heal previously speculated that she may even have had a nose job earlier in her career. Although her Hollywood career is still going strong, with more than 40 films under her belt, Nicole has said she tries not to let her work get in the way of her family and schedules film roles around her husband, country music singer Keith Urban. "I think I've reached a point in my life where I've slowed down a lot, so it's not difficult," Nicole said. "My priority is very much keeping my family together and not being away from them." A source close to the couple said Nicole has "never been happier and healthier."
