"Bones" season 10 cast Emily Deschanel's baby bump will be written into the show as Booth and Brennan will prepare for Christine's sibling.

"Bones" showrunner Stephen Nathan told TVLine in an interview that everybody is so happy with the news about Emily Deschanel is pregnant.

"As before, rather than try to hide this from a sophisticated audience, we are integrating her pregnancy into the show," he said. "Booth and Brennan, like most couples today, will continue to work, play and catch murderers - maybe they're unique in this respect - as their family grows."

"Bones" season 10 cast Emily Deschanel's baby bump was in shown in full glory during the party in celebration of the show's 200th episode on Monday. She is the sister of "New Girl" star Zooey Deschanel and wife of David Hornsby.

The 38-year-old actress was joined in the red carpet at the Mondrian Los Angeles in Beverly Hills by her co-stars, David Boreanaz, Tamara Taylor, Michaela Conlin, and T.J. Thyne.

"The actress certainly dressed for the occasion, baring her growing belly in a sparkling black frock adorned with gems as she arrived at Herringbone restaurant at the Mondrian Los Angeles in Beverly Hills," MailOnline said.

Pregnant Emily Deschanel, who plays Dr. Temperance Brennan in the series, was certainly blooming as she sported a smoky eye and nude lipstick while she posed for the cameras.

Stephen Nathan said they are not running away from "Bones" season 10 cast Emily Deschanel's baby bump and in fact, he thinks that this new development will only enhance the show. "Although I'm sure there will be a vocal group of fans eager to attack me, I hope they will be pleasantly surprised by what we have in store," he added.

"Bones," about a forensic anthropologist and her FBI agent husband who investigate cold cases using bones to look for clues, airs on Thursdays at 8 p.m. on Fox TV.
