Not sure how they’re going to cover this one up! Pregnant Jessica Biel’s growing baby bump was on full display while she filmed scenes in New Orleans on Monday, Feb.23. Justin Timberlake’s wife is in town to shoot her small role in Jason Sudeikis’ upcoming flick The Devil and The Deep Blue Sea.

Wearing a jean shirt and gray tank, the soon-to-be mom paired her dressed-down comfortable look with cargos and flats. 

“She’s very pregnant but she's really been a good sport,” an insider tells Us of the 7th Heaven alum, 32, who is due at the end of April. “She’s working long days with 5 a.m. call times and doesn’t complain at all. She doesn’t seem to be uncomfortable.”

Although she’s fully popped, Biel has remained dedicated to staying healthy, too. According to the source, she’s “very healthy” between takes, and snacks on fruit, avoiding the junk food offered at craft services.

“She’s very low-maintenance and hasn’t required anything extra at all,” the insider adds. “She is the opposite of a diva.”
