Tiffany hit it huge back in the late '80s by performing "I Think We're Alone Now" at malls across America -- and now, at the age of 41, she's doing it all over again.

...for a Klondike Bar.

The singer is the latest to join the ice cream company's "Klondike Celebrity Challenge," where fans dared her to return to the mall circuit and sing her big hit 26 years after it hit #1 on the charts.

toofab has the exclusive premiere of her video below:

The singer also talked to toofab's Brian Particelli about living in Nashville with her husband, son and 9 dogs, being a child star and revealed if she's sick of singing the same song over and over again.

toofab: How did this partnership with Klondike come about?

Tiffany: I was always a fan of Klondike. I used to have Klondike bars on my tour rider! I thought it was completely funny and wanted to know what fans wanted me to do. 

toofab: Why return to the mall?

Tiffany: The range of ideas [for the challenge] was really diverse, from sky diving to shaving my hair. A lot of people know me from singing in a mall, that's how I got started. So to go back ... I think the true ham in me came out. I went for it and it was a lot of fun.

toofab: Do you get tired of singing "I Think We're Alone Now"?

Tiffany: I never get burnt out singing it. I've done every version of the song you can do, acoustic, even a ska version. Even people now are rediscovering the song and it has its own life. I'm grateful!

toofab: Do you think it's harder to be a teen star these days? 

Tiffany: A little bit, there's so much to distract you. There is no place to hide, people are more in your business now than in the '80s. I didn't have to worry about people outside my home! 

toofab: You've done some crazy things in your career, from reality shows to SyFy movies, is there anything that made you go "No, I won't do that"?

Tiffany: There have definitely been things that didn't fit with my brand. Especially now that my fans are getting to know me as a woman, a mom.

toofab: You were part of the denim jacket craze of the '80s -- and now I hear you're starting your own line. Tell us about that.

Tiffany: Ha, I am! That's been in the works for 5 years now. I want it to be in specialty shops, in boutiques and on my tour. I'm trying to keep them one of a kind. I'm actually wearing one of my designs in the video.

toofab: How do you like living in Nashville and working at your own boutique?

Tiffany: Being born and raised in L.A., it seemed like I was always distracted. I never really had my home as my sanctuary. Coming to Nashville, I can do more of my songwriting, people can just come over for writing sessions, it's grounding. And opening up my own boutique is something I've always wanted to do.

toofab: As a SyFy movie veteran, what did you think about the "Sharknado" hoopla? 

Tiffany: I didn't see it ... but social media is fabulous! There's that opportunity to put something out there and people just start talking about it. You can build a fire. I think it's really awesome to throw something out there and it becomes a bit thing overnight!
