"A year ago Chiles met Don Henley, 32, the drummer with the Eagles, in her exercise class. "My image of musicians," remembers Lois, "was of groupies, tearing up airplanes and trashing hotels. That was the last thing I wanted to get involved with." But she did. She doesn't tour with the group ("Concerts are interesting the first few times"), though she and her dog, Ursula, guested at his Holmby Hills manse before finding their own cottage last month in Santa Monica. "I love him very much," she says, but has no plans for marriage or children. When they're together Chiles lets Henley cook. "I hate roles in relationships," notes Lois. "I like roles if you're being paid.""
