Is Jamie Dornan about to miss one of the most important events of his life? That might be the case as the Hollywood hunk is currently filming 50 Shades Darker with his co-star Dakota Johnson in Vancouver while his heavily pregnant wife Amelia Warner is back home in London with the couple's daughter.

According to London's Metro site on Sunday, Dornan looked rather "grim-faced" on the set of the film, leading to the speculation that he's worried that he might miss the birth of his second child.

It sure didn't help that the Vancouver weather wasn't cooperating as eyewitnesses say that Dornan and Johnson didn't look like they were enjoying themselves as they tried to huddle together under a big black umbrella.

Dornan's wife, meanwhile, has been nowhere to be seen, as fans can't help but wonder if she's getting ready to give birth any moment now. Many are speculating that her due date is in this month.

Also starring in the film is Hollywood newcomber Max Martini as Christian's bodyguard Jason Taylor, actress Kim Basinger as Christian's former lover Elena Lincoln and Bella Heathcote as Ana's love rival Leila Williams.

So far, Dornan himself has not made any comments about his wife's pregnancy.
