Actress Jessica Biel, who is expecting her first child with Justin Timberlake, is sourcing organic produce from local farms to maintain a balanced diet.

"She has been having deliveries from local farms so she can eat fresh organic produce and be as healthy as possible throughout the pregnancy," eonline.com quoted a source as saying.

"Being healthy is really important to her. She is very aware of the importance of eating well. She wants to have the best pregnancy possible," added the source.

The source also shared that Biel is in her third trimester now and she's "feeling good".

"She has stayed active during her pregnancy and tried to get in as much exercise as possible.

"She loves going hiking or on walks. She also does yoga at home and light stretching. She has spent a lot of time at home and plans to slow down on travelling in the next two months...she's embraced being a homebody and taking it easy," added the source.
