None-the-less, Hayden's stylist, Susie DeSanto, still had her work cut out making her bump appear smaller in scenes when Juliette is in her first trimester.
"It's been a big challenge. I mean, she's a really tiny girl and she's pregnant. There's nowhere for that baby to be but in the room!" DeSanto told Us Weekly.
"I think the most challenging part is maintaining Juliette's character while covering up [the extent of] her pregnancy.
"Juliette's style is body-conscious - she's always got the shortest skirt in the room. We've been buying bigger clothes and tailoring them down. That way, we can use the same designers, colors, and fabrics."
It was revealed in May that Hayden is expecting her first child with her fiancé Wladimir Klitschko.
Susie also let slip that Hayden's due date is in December and she was full of praise for Hayden's red carpet maternity style.
"I loved, loved, loved it," Susie said about the Lorena Sarbu dress Hayden wore to the Emmys in August [pictured above].
"It really was perfect - sexy, but classy and elegant. She's only 25 years old! Lots of times, I feel like girls on the red carpet are wearing things that are too mature for them, but Hayden always seems to be able to find the right balance."
