Newly-Single Katie Lee's Comfort Food Favorite

For the past 5 years, Katie Lee, 28, has been best known as Mrs. Billy Joel.

But since she split with the Piano Man in June, she’s been throwing her heart and soul into her already thriving culinary career. “This summer, I spent a lot of time in the kitchen,” says the cookbook author and food correspondent for CBS’s The Early Show. “I certainly find comfort in cooking and eating. And eating some more.”

Billy Joel’s split from wife Katie came as no surprise to Alexa Ray Joel, the music man’s 23-year-old daughter with Christie Brinkley.

“I have a pretty good woman’s intuition, so I could tell,” Alexa told PEOPLE at the sixth annual Wayuu Taya Foundation Gala at the Stephan Weiss Studio in New York City Wednesday night. “I know my dad very well.”

The couple announced their separation in a statement June 17 after nearly five years of marriage. Joel says she first heard the news from her dad.
