Idina Menzel and Kristin Chenoweth
Before they were Glee gals, Idina Menzel and Kristin Chenoweth were stars of the spell-binding Broadway play Wicked. Idina posted a pic of her and her longtime pal from back in the day, and may we say, this looks like a teen catalog ad from the '90s. The Frozen star tweeted on Dec. 18, 2014: "I always loved this shot. How beautiful is @KChenoweth here?"
