See Dolly Parton & Miss Piggy's Never-Before-Released Duet to 'I'm a Hog For You Baby' (VIDEO)

Time Life is celebrating Dolly Parton in a big way with Dolly: The Ultimate Collection, and TV Insider has a must-see sneak peek at the collection.

The award-winning country music star, actress, philanthropist, and American icon has been entertaining folks for 50 years and Dolly: The Ultimate Collection looks back on some of her greatest moments. Among those highlights? A never-before-released performance with Miss Piggy from the '80s in which the Muppet and Dolly don matching pink outfits while they duet to "I'm A Hog For You Baby."

And that's not all that's included in the 19-DVD set. The collection includes early performances from the '60s, her star-studded variety shows from the '70s and '80s as well as concerts, interviews, TV appearances, and more blockbuster collaborations.

"It's been an amazing journey and you'll find some of my most precious highlights included here in this collection." said Dolly.  "Thank you to the wonderful folks at Time Life for putting this together.  What a delightful trip down memory lane... just the hair styles and outfits alone are worth a look and I'm surprised there are still any rhinestones left in this world! I hope you enjoy these moments as much as I did."
