Harry Potter star Daniel Radcliffe has spent $ 4 million (GBP2 million) on a plush New York apartment - in a bid to kick-start his property portfolio. The 18-year-old actor purchased the spacious fifth floor property in a block designed by architect Jean Nouvel, according to reports. But Radcliffe has no plans to move in - he will be renting out the two-bedroom apartment for $20,000 (GBP10,000) a month.
