Heather Mills bizarrely wore a black wig and sunglasses at a New York airport Thursday.

The blonde former model fled the U.S. city in disguise just hours after her ex-husband Sir Paul McCartney and his new brunette love Nancy Shevell arrived. Heather was flying to Los Angeles, before she goes to Las Vegas to act as a judge in the Miss USA contest next week.

Lindsay Lohan was forced to cancel her appearance on the "Tonight Show" last night, but her absence was not felt because the show's host, Jay Leno had a substitute. The 21-year-old actress was replaced by comedian Rob Schneider and the show carried on.

Donning a blonde wig, black dress and an alcohol monitoring device strapped to her leg, Schneider took the hot seat as Lindsay.
