Justin Timberlake commands respect on the stage, but is he less than pumped to play dad?

Friends of the couple dish that mom-to-be Jessica Biel is concerned that her husband “isn’t ready to give up touring” and focus on fatherhood, reports The National ENQUIRER.

The couple has yet to make an official announcement about becoming parents, but the actress, 32, has been seen sporting a growing baby bump on the set of her film, The Blunderer.

While Biel is “beyond excited” about having a child, 33-year-old Timberlake has been focused on performing on his tour, which has been going on for over a year.

“They’ve spent little time together during Jessica’s pregnancy,” one pal said. “Justin pretends he doesn’t have a care, but you can see how antsy he is. He knows it won’t be long before his life changes…now she’s concerned it might be more than Justin can handle.”

As RadarOnline.com reported in October, Biel’s pregnancy was a long time coming. “Jessica has had tense times in the past when it comes to having a baby,” an insider said.
