A new addition to Brennan and Booth's growing family will arrive when "Bones" kicks off Season 11 this fall.

Executive producer Michael Peterson revealed that Brennan and Booth will welcome a baby boy in the upcoming season, reports Entertainment Weekly. The married couple already has a daughter named Christine, so it will be interesting to see how their newborn son will change the dynamic of their family.

"I won't say a name, but Brennan is going to have a boy and we're going to have fun with [her] as a mom," Peterson told EW. "Brennan is going to become the homeroom mom for Christine, which is just very fun for us -- the stories about what it's like to have Brennan be involved in school in that way."

Back in 2014, the show writers announced that they would incorporate Emily Deschanel's real-life pregnancy into the show. As the mother of two sons, the actress says that she is looking forward to see how the new baby will affect Brennan, Booth and Christine.

"When a new child is born into a family, it always affects the whole family," she said. "It's a huge change for everybody -- parents and the other siblings. They were the center of the universe for a while and now they have to share, and that's a challenge. Whether they show that directly or indirectly, it'll affect the other child," said Deschanel.

"Even with all the help that I get, I find it very challenging to have two kids," she continues. "Trying to make sure you have the time for both of them, and juggling all the different things. You have another child who has activities and school and all that. I think you'll see storylines revolving around that as the season goes on."

According to CarterMatt, there will be a time jump between the Season 10 finale and the Season 11 premiere.

"Picking up six months after the Season 10 finale, Brennan and Booth have moved on to a new town and new jobs, having given up their old life and settled into a blissful death-free existence. But a murder unlike any other draws them back to investigate with their former colleagues at the Jeffersonian and FBI," states the synopsis.

Season 11 of "Bones" will premiere on Thursday, Oct. 1 at 8 p.m. ET on Fox.
