CELEBS FROM `DEPTHS' OF THEIR VERY SOULS.

Byline: - David Kronke

``Celebrity Autobiography: In Their Own Words'' offers the monumentally self-absorbed smugness of such celebrated memoirists as Burt Reynolds, Elizabeth Taylor, David Cassidy, Sylvester Stallone, Kenny Loggins, 'N Sync, Ivana Trump and George Takei. Gaseous passages from the works of these literary lions are amusingly performed by Fred Willard, Cheryl Hines, Kevin Nealon, Andrea Martin and Jay Mohr, the last of whom, oddly enough, has written his own self-aggrandizing book, reminding one of the old adage about glass houses and stones.

Hilarious as this can be - and it's pretty ripe stuff - perhaps the funniest thing about it is the generously politic description of the show from Lauren Zelaznick, president of the cable network Bravo, who calls ``In Their Own Words'' ``a refreshing and unique look at the many layers of celebrity culture.'' Which is the nicest possible way of saying, ``These celebrities have not only lost all touch with reality, but they want to prove it to their incredulous readership.'' One quibble: How could they possibly have overlooked Klaus Kinski's epic of self-loathing - heck, of everything-loathing - which its publisher originally withdrew due to legal concerns?

``Celebrity Autobiography: In Their Own Words'' premieres at 10 tonight on Bravo.
