He exclusively told BANG Showbiz: "She just turned so quickly into wedding planner from fiancee, I can't f***ing keep up. I'm going back to London for the BAFTAs on Sunday from Ireland where I've been filming and I know everything will already be done, she is on it.

"We have the venue booked, the date picked, she's looking at menus, I mean she's all over it. I feel like all I'm getting really is the check. She's a very clever woman, so I'm just going to leave her to it."
Chris is leaving all the organization up to Dawn and has no idea what to expect when their wedding day arrives, although he has been harboring a few guesses.
He joked: "I imagine at this stage it's all going to happen in a hot air balloon, just me, her, and Jedward."
Along with leaving all of the wedding arrangements up to his fiancee, Chris has also left his best man to plan the bachelor party.
He explained: "I haven't even talked to my best man about what his thoughts are but I'll definitely do something. I think we're going to leave puppies out of it, but chocolate fountains can always be welcome.
The 32-year-old comic star is up for the Orange Rising Star Award at the BAFTAs on Sunday.
Chris is up against Chris Hemsworth, Tom Hiddleston, Adam Deacon and Eddie Redmayne in the category which is voted for by the public.
