She's a style icon in her own right, but Katie Holmes' transformation into America's most fashion forward First Lady, Jackie O, is nothing short of stunning, and RadarOnline.com has the photos.

With her bobbed brown hair, pearls, pill box hat and proper attire, the former Dawnson's Creek star bares a striking resemblance to the one and only Jacqueline Bouvier Kennedy Onassis, who she is playing in the TV miniseries, The Kennedys.

But ditching her jeans and gym wear in favour of the ladylike wardrobe of the President's wife, wasn't the tough part for Katie, who admits taking on the character was the most intimidating part.

"It's been amazing and a little overwhelming because she is such an icon and so important to our country and so many people have fun memories of her," she said. "In doing the research, I learned so much about her and my adoration for her only grew, so it's been really fun. It's always great to play a character that you love."

Katie has been snapped on the set of the miniseries - in which she stars alongside Greg Kinnear - in an abundance of clothing imitating the first lady's favorites.

But possibly the most shocking promotional picture is the image of her wearing the hot pink suit, identical to the one she wore when John F. Kennedy was shot.

Mrs. Tom Cruise isn't the only brown eyed beauty to play Jackie O however. RadarOnline.com also has photos of some of the other impressive transformations.
