Whitney Houston Signature Barbie Doll (Courtesy Mattel Inc.)It’s the greatest doll of all: The Whitney Houston Barbie is here. The Whitney Houston Barbie Signature Doll is modeled on Whitney’s look in the video for “I Wanna Dance with Somebody (Who Loves Me)”: She’s wearing a purple tank dress, drop earrings and colorful eye makeup and big curly hair, and she even comes with a microphone stand. The $60 doll was unveiled Aug. 8 at the fifth Legacy of Love Gala, a charity event hosted by the Whitney E. Houston Legacy Foundation. It’s now available at Target stores, and online at Amazon, Walmart, Target and Mattel Creations. In other Whitney news, there’s a new expanded digital album collecting all of Whitney’s #1 Billboard hits across multiple charts.
