Katie Holmes Sports Jackie O's Baby Bump

Katie Holmes holds onto her fake baby bump while filming a scene as Jacqueline Kennedy in the upcoming History Channel miniseries The Kennedys on Wednesday (July 21) in Toronto, Canada.

The 31-year-old actress skipped rocks into a lake with co-star Greg Kinnear during one scene.

Katie told Us Weekly that it has been a lot of fun wearing Jackie O‘s “magnificent” clothes. “I feel so lucky,” she shared. “We have these wonderful seamstresses who are creating beautiful dresses that are obviously replicas of real things she wore. Armani made two dresses for me to wear.”

Katie even brought along her daughter Suri Cruise to the set!
