Katie Holmes unrecognizable as Jackie Kennedy on set of 'The Kennedys: After Camelot'

Katie Holmes Celebrates Daughter Suri Cruise's 10th Birthday - See Her Sweet Gift!

Katie Holmes is a chameleon in front of the camera.

The 37-year-old actress was spotted in Canada on Wednesday sporting an entirely new look. Fans are used to Holmes looking young and vibrant, but while filming The Kennedys: After Camelot, she channeled her inner Jackie Kennedy, whom she plays in the Reelz Channel miniseries, and took on a more elegant and slightly aged look.

Jackie O was known for her iconic style, grace and great hair and now Holmes has completely transformed into her, making her almost unrecognizable. While shooting this week, Holmes donned a cream coat with gorgeous button detailing fit for the first lady. The coat covered a black turtleneck frock.

The most shocking part, however, was Holmes's hair. For her Wednesday shoot, the mother of one switched out her normal dark locks for a sleek 'do. She showed off more of her face and gave us a peek at her big earrings with a pushed-back hairstyle cut into a longer bob.

Even though her revamped style is new to fans, it is somewhat old for the actress. The new miniseries will be the second time that the former Dawson's Creek star has played Kennedy. She previously took on the role on Reelz Channel's other miniseries, The Kennedys back in 2011. This time around, Holmes will be starring alongside Brett Donahue, who will be playing John F. Kennedy Jr. in the four-part series.

Holmes might be stepping back into a part she is comfortable playing, but she will be switching things up behind the camera. She will not only be acting onscreen, but she is an executive producer for the project and will be directing one of the installments.

Holmes isn't the only woman who looks like the beloved first lady. Her granddaughter, Rose Kennedy Schlossberg, is her spitting image. See her uncanny resemblance below.
