We all know and love actress Elizabeth Berkley from the 90's hit show Saved By The Bell ... and others know her from the sexy flick Showgirls.

Now the 38-year-old actress is gearing up for her new real-life role as mom. Elizabeth left her Hollywood pilates class in flip flops while holding her sneakers in front of her belly, but we can still see that growing bump!

She and hubby Greg Lauren announced the pregnancy last month. Berkley Tweeted, "In life there are moments you cherish forever and this is one of them. Greg and I are so excited to be expecting our 1st child this summer."

See more photos of Elizabeth and her baby bump in our gallery below.

Elizabeth Berkley is about to take on her greatest role yet -- parenthood!

The Saved by the Bell star and her gorgeous fashion designer hubby, Greg Lauren -- aka Ralph Lauren's nephew -- are "thrilled" to be expecting their first child, her rep confirmed to People on Monday.

Berkley, 39, is in her second trimester and is due this summer.

Congrats to the parents-to-be!

Elizabeth Berkley has come a long way since her Showgirls days ... the actress-turned-author is now at the top of the New York Times Best Sellers list with, Ask Elizabeth: Real Answers to Everything You Secretly Wanted To Ask About Love, Friends, Your Body ... and Life in General..

The actress spent part of her afternoon on Thursday having lunch with a male friend, but appeared very attentive and focused. Could Berkley possibly already be working on a follow-up to her self-help book?

In Ask Elizabeth, the 39-year-old offers insights and encouragement to teen girls. The popular inspirational book's design was a collaboration between Berkley and her husband, Greg Lauren, Ralph Lauren's nephew.

With her many years of experience in the cut throat, superficial entertainment biz, it's good to see Berkley putting those lessons to good use ... just as long as she is not offering teen girls stripping advice.

A pregnant celebrity was recently caught with her self-help book. Find out who it is ... after the jump!

And on a rainy day! Not a smart move, Elizabeth Berkeley. The former Saved by the Beller ran errands in Bev Hills yesterday but neglected to conceal some private parts. Not that there's any mystery about her bod - after all, the Showgirls: 15th Anniversary Sinsational Edition comes out in June!

Whether she was Saved by the Bell or just your average Las Vegas Showgirl trying to make it big, we've always held a special place in our heart for Elizabeth Berkley...

And now you should, too! The lovely "actress" was spotted leaving a blood bank in Los Angeles this week after making a contribution.

Is it just us or does SBTB deserve a reunion show? If they're giving us more 90210, they can give us more Saved by the Bell!

We bumped into Elizabeth Berkeley and her hunky hubby, artist Greg Lauren, outside of Sushi Kiyono the other day. Check out the bag she's carrying - what a positive message! Jessie Spano may be long gone, but it's great to see Elizabeth working just as hard for a cause!

We're talking about for the absinthe, of course!
