Who would have thought that Kelly Kapowski would have grown up, gotten married to someone other than Zack, and had a baby?

That's exactly what Kelly's alter-ego, and real-life counterpart, Tiffani Amber Thiessen has gone and done!

The 39-year-old former "Saved by the Bell" star took her adorable 3-year-old daughter Harper (she has something in common with Victoria Beckham!) to a Doc McStuffins children's event Wednesday at a Disney Store in New York.

The Tiffani mini-me was the spitting image of her gorgeous mom with matching bangs and the same green eyes. Thiessen, who's married to Harper's dad, actor Brady Smith, coordinated her and her daughter's outfits so that they both wore contrasting but complementing summer colours, with Tiffani in a simple white frock and eye-grabbing blue-and-pink blazer and little Harper in a white-and-green dress with cute gold flats.

We're a bit surprised that the mom isn't sporting the on-trend crop top which she herself arguably started back in her "Saved by the Bell" days. Who are we kidding? Kelly was the Queen of the crop tops!

Being a mom doesn't stop the former "Beverly Hills, 90210" star from being sexy though. The actress recently stripped down to her skivvies for a sexy photo shoot for the website Me In My Place.

So how does she keep her amazing body in shape? The "White Collar" actress told Celebuzz that it's not just about going to the gym.

"I cook a lot at home, which I think a lot of the time when you cook at home you can really know what you put into your body," Tiffani said. "(Also) running around with a kid definitely helps."

Hello, supermom!

  • Tiffani Thiessen (Kelly Kapowski)

    Bayside's resident cheerleader probably wasn't shaking her pom-poms when her roles mostly consisted of TV movies and some TV series pinch-hitting -- joining the casts in later seasons of "Beverly Hills, 90210," "Two Guys, a Girl and a Pizza Place" and "What About Brian." But it was her scantily-clad role as <a href="http://www.youtube.com/watch?v=zs2x2B-MTw8" target="_blank">Honey DeLune in 2000's "The Ladies Man"</a> -- one of the worst of the "Saturday Night Live" skits-turned-movies -- that's the real dark spot. Thank goodness she's found her footing on USA's "White Collar."

  • Mark-Paul Gosselaar (Zack Morris)

    What's the fastest way to shed your teen heartthrob image? Play a college rapist. At least that's what MPG did when his "Saved By The Bell" stint was over. The actor starred alongside fellow teen idol and "Full House" alum Candace Cameron in the <a href="http://www.youtube.com/watch?v=tbSbQQ39AjU" target="_blank">1996 made-for-TV movie "She Cried No."</a> Fans didn't stop worrying about his decision-making skills until he became one of the good guys again and joined "NYPD Blue" several years later. These days, he's playing attorney Peter Bash on TNT's "Franklin & Bash."

  • Mario Lopez (A.C. Slater)

    Mario Lopez went from being the hit of mall tours as jock A.C. Slater to playing diver Greg Louganis in a made-for-TV movie, a beach bike cop in "Pacific Blue," a doctor on "The Bold and the Beautiful" and a super-kinky MD on "Nip/Tuck." But it's his current gig <a href="http://www.extratv.com/page/about/mario-lopez/" target="_blank">hosting "Extra"</a> -- which ironically shoots at a mall in L.A. -- that makes his full-circle story a bit cringe-worthy.

  • Elizabeth Berkley (Jesse Spano)

    Much like the extreme route MPG took to erase his clean-cut image from "Saved By The Bell," Elizabeth Berkley went from brainy Jesse Spano to taking it all off to play a stripper -- excuse us, <i>exotic dancer</i> -- for <a href="http://www.youtube.com/watch?v=YCCjdUeMAO0" target="_blank">"Showgirls," one of the best worst movies ever made</a>. The mother of one and animal rights activist hasn't appeared on screen in a couple of years, but she did set up a self-help program and website for teen girls called <a href="http://www.ask-elizabeth.com/" target="_blank">Ask-Elizabeth</a> after her husband commented on the number of young women who came to her asking for advice.

  • Dustin Diamond (Screech Powers)

    Dustin Diamond has had quite a long resume, full of roles playing himself since he lovingly annoyed us all as Screech Powers, but that's probably because he couldn't shake the character he played for so many years on "Saved By The Bell" and all of its spin-offs. Money problems, legal issues and a porno later, it's still his <a href="http://www.youtube.com/watch?v=UJs4hyHNEys" target="_blank">s***-starting stint on "Celebrity Fit Club"</a> that truly tarnished his image. However, Diamond is currently working on a few independent films, including "Hamlet A.D.D.," a reimagining of Shakespeare's play.

  • Lark Voorhies (Lisa Turtle)

    Lark Voorhies became a daytime diva, starring on "Days of Our Lives" and "Bold and the Beautiful," where she sadly never overlapped with Mario Lopez. But after playing fashionista Lisa Turtle for so many years, it was her <a href="http://www.huffingtonpost.com/2012/05/11/lark-voorhies-lisa-turtle-photos_n_1509157.html" target="_blank">odd appearance in a 2012 interview</a> that got Voorhies the most attention since her Bayside High days and caused her to admit that she's been struggling with <a href="http://www.huffingtonpost.com/2012/11/08/lark-voorhies-bipolar-disorder-save-by-bell-actress-denies-mental-health-issues_n_2094381.html" target="_blank">bipolar disorder</a>.

  • Dennis Haskins (Richard Belding)

    Dennis Haskins’ post-"Saved by the Bell" resume is full of questionable credits -- did Mr. Belding really need to be there for "SBTB" movies "Hawaiian Style," "Wedding in Las Vegas" and "The College Years" spinoff? Wasn't "The New Class" enough? But it's <a href="http://www.amazon.com/Karaoke-With-Favorite-Principal-Dennis/dp/B002IRDDQG" target="_blank">his 2009 karaoke CD</a>, based on his reputation for frequenting an L.A. karaoke bar and capitalizing on his Bayside High character, that caused the most concern. Haskins has returned to his TV roots in recent years, appearing on "How I Met Your Mother" and <a href="http://www.huffingtonpost.com/2012/05/08/mr-belding-mad-men-guest-stars_n_1501096.html" target="_blank">"Mad Men" ... albeit in the role of Cool Whip Test kitchen scientist</a>, but we'll take it.
