Despite rumors of a marital rift, rocker Billy Joel and his wife Katie Lee Joel are doing just fine, says their pal Emeril Lagasse. “They’re a very cute couple, and dear friends of mine. I was with them a couple of weeks ago in Miami. They were perfectly fine!” the Fine Living Network’s Emeril Live chef told In Touch at the Food Bank for New York City’s Sixth Annual Can-Do Awards Dinner on April 21. Though former Top Chef host Katie, who has been married to Billy for more than four years, arrived without her much-older husband, the brunette beauty was all smiles at the New York event honoring Jon Bon Jovi. “She seemed happy!” an onlooker tells In Touch. A tabloid recently claimed the pair was fighting over Katie’s close friendship with designer Yigal Azrouël.
