Reports surfaced in October that Jessica Biel is expecting her first child with husband Justin Timberlake, although the couple has yet to confirm the rumors.

Biel, 32, left Tinsletown over the weekend to film upcoming project "The Blunder" in Cincinnati, where she stayed bundled up between filming scenes due to cold temperatures, reports E! Online. The possibly pregnant star was spotted wearing a puffer coat and Ugg boots in between filming scenes, hiding the baby pink A-line dress worn for her character role.

It was impossible to see a baby bump even when Biel removed the coat for filming, leaving many disappointed.

Even though niether Biel nor Timberlake, 33, have confirmed or denied pregnancy rumors, Biel's friend and InStyle editor Ariel Foxman posted an Instagram picture with the actress.

"Congrats @jessicabiel on your impending motherhood ... Looking forward to the red carpet maternity style pix to come #tbt," the caption said.

Foxman has since removed the rather revealing picture.

Two years after the couple said "I do" in Italy, speculation that Biel was expecting came when photos of her hiking with Timberlake in New Zealand seemed to show a baby bump.

Blind Gossip recently reported that Biel was past her first trimester but was holding off on the pregnancy announcement due to her new business venture, Au Fudge. She reportedly does not want pregnancy news to outshine publicity for the kid-friendly restaurant located in Santa Monica, California.

Pregnancy rumors aside, Biel is working hard with co-stars Eddie Marsan ("Ray Donovan"), Patrick Wilson and Haley Bennett on production of the murder mystery "The Blunderer." It is based on Patricia Highsmith's 1954 novel of the same name and tells the story of a successful man (Wilson) who has it all until the day his wife's (Biel) dead body is discovered at the bottom of a cliff. The investigation into his wife's death leads to intense scrutiny which causes him to commit one blunder after another until his perfect life is derailed.
