Jessica Biel has been "very low-maintenance" on the set of her new movie.
The 32-year-old actress, who is set to give birth to her first child in "late March or early April," is currently filming a small role in the upcoming film, 'The Devil and The Deep Blue Sea,' alongside Jason Sudeikis in New Orleans and hasn't asked for any special treatment.
A source said: "She's very pregnant but she's really been a good sport. She's working long days with 5 a.m. call times and doesn't complain at all. She doesn't seem to be uncomfortable.
"She's very low-maintenance and hasn't required anything extra at all. She is the opposite of a diva."
The insider also told UsMagazine.com that the brunette beauty, who is married to Justin Timberlake, is sticking to "very healthy" food between scenes and has avoided indulging in junk food at craft services.
Jessica has kept busy throughout her pregnancy, as she is also planning to open her first child-friendly restaurant, Au Fudge, in Los Angeles shortly after this gives birth.
Despite being in her third trimester, 'Mirrors' hitmaker Justin only confirmed he and the actress are expecting their child last month and insiders previously revealed they wanted to keep the news a secret for as long as possible to make sure their baby was healthy.
