Talk about superwoman! 

Jessica Biel's new film The Book of Love opens in theaters Friday and Justin Timberlake's other half stopped by at Jimmy Kimmel Live! to talk about producing and acting in the film—all while eight months pregnant.

During the appearance, the actress opened up about her responsibilities for the drama, which features a soundtrack from Timberlake and has been 10 years in the making.

"My responsibility for this film was to get this thing going. We've been working on it for 10 years," the mom of one explained to Kimmel, listing her duties as producer. "[We were] like trying to get people to fund it, trying to get a cast. Financiers, distributors, trying to get a crew together, finding the locations, and making sure everyone is ok and happy, nobody hates each other, and everyone is fed."

As if that wasn't challenging enough, the 34-year-old also revealed that she was eight months pregnant with her son, Silas, when she started filming the movie.

"It was crazy," the star admitted. "It's a bad idea. You don't want to be doing anything when you're eight months pregnant, let alone living in New Orleans during Mardi Gras, not partying with anybody else."

When the brunette stunner finally got the project off the ground, she had to make a few sacrifices because of her condition. "I could only shoot for five days, so I was there for the pre-production basically," Biel explained, revealing that she had been told by the doctor not to fly past a certain date.
