It's probably never good to wake up and see your significantly younger wife's face in the Daily News in an article sprinkled with your very own song titles like "Movin' Out" and "It's a Matter of Trust." Allegedly the 27-year-old Katie Lee Joel has been cheating on the 59-year-old Billy Joel with fashion designer Yigal Azrouel. A source told the paper the two have been together for a while, and “Katie often stays at their apartment in NYC alone, while Billy likes to live in their Long Island home. They’re rarely together. And Katie likes it like that. She wants her freedom.” The crooner has heard of the designer, whom he at first assumed was gay, and the relationship rightfully has him furious. The source adds that Azrouel has “slept with several high-profile female fashion editors. It’s understandable that everyone would think he’s gay, as he’s a man of fashion in NYC, but he isn’t." Most recently, Katie (sans wedding ring) and Yigal were spotted together at a Museum of Natural History gala.
