Getting down on one knee, the 61-year-old popped the question at his girlfriend’s 21st birthday party.
Robyn Delabarre is filmed sitting on a chair as her beau gets down while wearing a white shirt completely unbuttoned.
The beauty, who is a stripper, immediately says yes and throws her face into her hands.
Sharing the video, Robyn wrote: “My 21st birthday, a night I will never forget, wow.”
Christopher played Gail Platt’s husband Brian Tilsley on the ITV soap, before he was killed off in a brutal stabbing storyline in 1989.
He went on to work at the famous Covent Garden strip club Stringfellows.
Years later he became a manager at a gentleman’s club, Secrets Hammersmith, where Robyn works.
For seven months the pair had to keep their relationship a secret due to her being his employee.
Recently returning from a romantic trip to Mykonos, Robyn shared with pals: “My husband to be!
“I love you and I couldn’t care less what anyone has to say”
“It’s been a crazy seven months, a secret we had to keep because of our jobs but you have made me the happiest girl alive you’re amazing to me.
“I’m so lucky to have you in my life. I’m so glad you’re mine.
“I love you and I couldn’t care less what anyone has to say. I love you with all my heart.
“Thank you for doing everything you do for me Chris [sic].”
