Shortly after actor Chris shared the video, Dawn took to Twitter to say: "Thought we'd better mention it, before I got O'Busted!"
Chris is best known for starring in The IT Crowd and hit movie Bridesmaids, while Dawn is a writer and journalist. She was previously Dawn Porter, but added the 'O' when the couple got hitched.
Congratulations, both!
