Former teen sensation Tiffany is back and better than ever! The superstar singer performed her hit song "I Think We're Alone Now" at malls across America in the '80s for thousands of screaming fans, and now, 26 years later, the 41-year-old is doing it once again. But this time it's not to promote her pop-star career. She's actually participating in the "Klondike Celebrity Challenge," where she was dared to perform the No. 1 hit on a mall circuit, just like in the good ole days.
