Golf legend GREG NORMAN is facing a multi-million dollar fine from American tax inspectors over his use of a private jet. Norman - who is dating ex-tennis player Chris Evert - is currently being investigated by the Inland Revenue Service (IRS) as part of his divorce battle with estranged wife of 26 years, LAURA. The tax officers are studying the logs of Norman's Gulfstream G550 jet and Bell 407 helicopter, attempting to discern whether the plane was used for the business purposes stated on official tax documentation. Due to strict tax regulations, any discrepancies found by inspectors could lead to the golfer being fined if the vehicles are found to be mainly used for leisurely pursuits. Evert divorced Olympic skier-turned-sport fisherman ANDY MILL in December (06), and was first spotted with 51-year-old Norman in Sydney last month (JAN07).
