No question Faith Hill and Tim McGraw are both dolls, but literally?   The superstar country couple will celebrate their 15th wedding anniversary in October by becoming Barbie dolls.   EW reports Mattel will officially release the latest Barbies, known as the Tim McGraw and Faith Hill Doll Gift Set, next month at BarbieCollector.com at a mere $69.95 a pair.  Linda Kyaw, a designer for Barbie Collector said Tim and Faith were involved from the get go.   “Tim and Faith sent us photos of every detail” of their outfits for the dolls, Kyaw says, “including Tim’s complete suit, piece-by-piece; and Faith’s dress, make-up, and clear shots of her hair preference. The couple knew exactly what they wanted to see in doll form, and they helped us achieve the best possible results.”    Read all about it here. Tim and Faith aren't the first celeb Barbies.  Farrah Fawcett and the cast of Twilight are also immortalized in plastic.  "Our vision is to capture the true essence of the celebrity — and I think we did just that with Tim and Faith."  What do you think?
