That she does: Curtis emerges, statuesque, in a cream-colored confection that showcases her hourglass figure. Standing in front of the mirror, Curtis pushes and prods her flesh like Play-Doh. She's concerned that when she leans over she'll spill out of her top. "She has such divine bosoms," says Tyler. "Yeah," she replies, "but they need somewhere to sit." Tyler fusses with a chiffon sleeve; the dress was originally designed to be sleeveless, but Curtis doesn't want to bare her arms. She makes the flab underneath her bicep wiggle. "See, this is after going to the freaking gym!" she cries. At 4:30, Curtis finally heads back to Santa Monica. "My personal relationships are the absolute center of my life," she says. "And then the rest of all of this can swirl around, and I don't have to worry about it." She's eager to hear about 8-year-old Tom's day at school, find out how Annie's SAT tutoring is going and greet her husband, mockumentary mastermind Christopher Guest ("Best in Show," last year's "The Mighty Wind") after his golf game. She attributes the longevity of her marriage to "growth, hopefully. Parallel, mutual, intersecting growth." That doesn't mean we're likely to see a professional collaboration between Lord and Lady Haden-Guest (yes, he's titled). "He works in improvisational comedy," she says. "I wouldn't even for a second know how to do that."
