One Chick Hatches The Dixie Chicks have a new roadie. The country music trio's lead singer, Natalie Maines, gave birth to her first child, Jackson Slade Pasdar, in Austin on Thursday. The father is Maines's husband, actor Adrian Pasdar.

Young Jackson entered the world weighing 6 pounds, according to the group's publicist. Mother and baby were said to be doing fine.

The labor lasted a comparatively brief four hours. Maines's band mate Emily Robison said Jackson "has sandy blond hair and Natalie's nose. She made us very jealous. It was a very easy and fast delivery." The band is currently on hiatus, with a new album likely next year.

A Worldly Musician United Nations Secretary-General Kofi Annan, we now know, likes two things: world peace and jazz.

Annan has appointed Wynton Marsalis a U.N. "messenger of peace," an honor that also has been bestowed on the likes of Earvin "Magic" Johnson and Muhammad Ali. The position effectively makes Marsalis an envoy for the global organization, publicizing its work and speaking out on behalf of its causes. Individual U.N. agencies have named celebrities to campaign for them, but only eight people have been chosen by Annan to speak for the U.N. as a whole.

Marsalis, music director of the Lincoln Center Jazz Orchestra, apparently is one of the secretary-general's favorite musicians, according to reports. He performed at the U.N.'s New York headquarters in 1998.

Lordy, Lordy, Look Who's 40 The latest Us Weekly magazine, due out locally on Monday, features on its cover a rather unusual piece of celebrity minutiae. It seems that half of Hollywood is turning 40 this year. On the cover are actors Heather Locklear, Meg Ryan, George Clooney, Scott Baio and Michael J. Fox, as well as onetime child stars Leif Garrett, Susan Olsen and Mary McDonough.

But that's hardly it. Also born in 1961 were Eddie Murphy, Dylan McDermott, Dennis Rodman, Jennifer Tilly, Julia Louis-Dreyfus, James Gandolfini, Boy George, Laurence Fishburne, Woody Harrelson, k.d. lang, Fabio and Kim Delaney, to name a few. Add to that list track star Carl Lewis and gymnastics icon Nadia Comaneci. Furthermore, non-dairy creamer and disposable diapers debuted that year, and perhaps most significantly, the Ken doll.

Coincidence or alien conspiracy?
