Jessica Biel turned 33 with a baby bump to join the birthday party. Excited future dad Justin Timberlake celebrated with his wife and pals, reported Us Weekly.
The birthday celebration was simple, and Jessica was careful to stay on her pregnancy diet, said an insider.
"Everyone ate dinner and toasted Jessica, even though she couldn't drink. At the end of the evening, Jessica opened up gifts," revealed the source.
And Timberlake demonstrated just why he'll make a great father by protecting both wife and baby bump, added the insider.
"He was protective and shielding Jessica. She was walking slowly in her heels but she was very happy and said she had had the best night."
To share his feelings, Justin posted a sweet birthday message on social media with a photo.
"Happy Bday to the sweetest, most GORGEOUS, goofiest, most BAD-A** chick I know. You make me smile 'til it hurts. I love you like crazy! — Your Huz."In turn, Jessica shared her thanks for all the happy birthday wishes with her own sweet photo and message.
"Birthday smooch. Thanks everyone for all the good wishes! #tuesdayswithtina"Justin was the one to make Jessica's pregnancy announcement, and he chose his own birthday to share the baby bump news, reported E News.
"Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets"Jessica has been dedicated to following a pregnancy fitness and diet regime since she first knew that she was expecting, said an insider.
"She has been having deliveries from local farms so she can eat fresh organic produce and be as healthy as possible throughout the pregnancy. Being healthy is really important to her," said the source.
Because Jessica recognizes the link between a healthy pregnancy and nutrition, she's sticking to her diet faithfully, added the insider.
"She is very aware of the importance of eating well. She wants to have the best pregnancy possible."In addition, Jessica has created a pregnancy fitness routine that ranges from walking to yoga, which provides her with the ability to stay flexible.
"She's in her third trimester now and feeling good. She has stayed active during her pregnancy and tried to get in as much exercise as possible," said the source.
As the Inquisitr reported, Jessica Biel follows a Paleo diet that consists of locally sourced, unprocessed food. It's also gluten-free, and prior to her pregnancy, Biel revealed why she believes in a Paleo diet.
"Eating Paleo just leans you down and slims you up and takes that little layer of fat and water-weight right off your body," said Jessica.
