Property tycoon Donald Trump has sparked controversy after declaring he would date his sexy daughter IVANKA if they were not related. Trump insists he would be comfortable if the 24-year-old model decided to strip off for men's magazine Playboy, because he would be the first to ogle her if he wasn't her dad. He says, "If she posed, it would be fine. She does have a very nice figure. "I've said if she wasn't my daughter, perhaps I'd be dating her." Trump's spokesman has attempted to explain The Apprentice reality star's comments, saying, "He was making fun of himself for his tendency to date younger women. It's a sense of humour that people don't see all the time."
