Now known as Deborah Gibson, the 44-year-old singer was most seen in the fifth installment of "Celebrity Apprentice" (she was fired in round 7) and had a cameo in the film "Rock of Ages." Prior to that, she had spent most her time palling around with Tiffany on a 2011 summer tour, and co-starring in the excellent Syfy movie "Mega Python Vs. Gatoroid." —XFINITY Entertainment Staff (Photo: Paul A. Hebert/Getty)
