Tiffani Thiessen strikes a pose with a Just Jared coaster at Comic-Con held at the San Diego Convention Center on Thursday (July 22).

Here’s what the 36-year-old actress and new mama had to share exclusively with JustJared.com:

JJ: You have done some very different characters in your career: Kelly (Saved by the Bell), Valerie (90210), and now Elizabeth in White Collar. What’s your favorite thing about each one of these characters?

TT: Very different, yes. I think Kelly played the very iconic popular girl next door, which who wouldn’t want to play that? To go from that and play the total opposite was really fun to play the bad girl (Valerie), who wouldn’t want to play that! Now, with this character (Elizabeth Burke in White Collar) this one is closest to home for me. I feel like Elizabeth is much more like myself, so that’s actually a really nice thing to play right now.

JJ: What’s coming up next for you?

TT: Tons of stuff! I just had a little girl 5 weeks ago so that’s taking a lot of my time right now. I’m also promoting the show and going back next week to finish off the season in New York, so that’s doing a lot. I’m also starting a children’s furniture line called Petite Nest for the end of this year, so I’ve got a lot on my plate.

JJ: How is life different now with a baby?

TT: You don’t have poopy diapers and spit up before you have a child, so it’s a lot of that right now (laughs).

JJ: Going back to White Collar, what’s the most exciting thing about the show?

TT: For me, personally, it’s just the cast. I’ve done a lot of shows in my 26-27 years of doing this, and it’s one of the first shows that I can say that we really get along, all of us. We have a really good time together and we’re excited to go to work every day. I haven’t been able to say that about every show that I’ve been on.

JJ: What would be a dream role?

TT: You know what’s funny, in the past, when I was a teenager and in my early 20’s, it was like the James Bond girl, but now my life has changed and that’s not really an aspiration for me anymore – it’s more about just doing good work. Doing a character like Elizabeth right now is kind of where I am, playing someone very down to earth and very real and not to out there. My life is different now.

Julie Benz proudly holds up JustJared.com’s special coaster at Comic-Con 2010 on Saturday (July 24) in San Diego, Calif. Here’s what the 38-year-old actress had to share with us exclusively:

On her new show: No Ordinary Family premieres September 28th at 8pm on ABC. It’s been such an exciting transition for me to go from death on Dexter, to Desperate Housewives, and now onto this new show.

You died on Angel, then Dexter! Why do they keep killing you?? How many deaths! (laughs) You know, my mom asked after my demise on Dexter, “Could you please be put on a show where they’re not gonna kill you off?” So I said “Okay, I’m looking for a comedy.” (laughs)

What attracted you to No Ordinary Family? What I really love about my character Stephanie is that she’s a very strong active, female character. She’s a modern day woman, the bread winner of the family, and a working woman with a type A personality. Stephanie is also trying to be a good mother and a good wife, but she struggles woth that because there’s just not enough time in the day. I think it’s a role women can relate to universally — balancing work and the home, and being a mother and a wife. That’s what I really loved about it!

What are your superpowers on the show? My character develops super speed. After a plane crash, we all develop a super ability and my character develops super speed.

Are you running a lot? I am! I am actually running a lot in my own life now because I have to stay in top physical condition now that I have to run everywhere.
