Don't tell Nate -- he'll probably go on a bender. ''Six Feet Under'' star Rachel Griffiths is pregnant, her publicist told ''E! News Daily.'' No word on when the stork is dropping by, but the child will be the first for the 35-year-old actress and her husband, artist Andrew Taylor. The Aussie couple married last New Year's Eve.
It's not clear what her pregnancy means for the HBO show, whose third season ended last month with Griffiths' Brenda starting a tentative relationship with a French horn-playing neighbor, and with her ex-fiancé Nate (Peter Krause) spiraling into a sex-and-booze binge as he finally learned that his missing wife Lisa (Lili Taylor) was actually dead. In a recent interview, series creator Alan Ball said on HBO.com that he had not yet ''mapped out'' the fourth season, which is not likely to air until next March. So Ball will have some time to figure out whether to write the pregnancy into the show (could a Nate and Brenda reunion be in the works?) or to hide Griffiths' belly behind the coffins and flower arrangements at the Fisher family funeral home.
