Isaiah Mustafa, who found internet stardom as the star of the popular Old Spice body wash and after-shave commercials has spent the last two days replying to Twitter questions from fans.
In addition to offering witty videos to questions from actress Alyssa Milano, blogger Perez Hilton and TV host Ryan Seacrest, Mustafa replied to a request from tweeter Johannes S Beals to propose to girlfriend Angela A Hutt-Chamberlin.
"Angela A Hutt-Chamberlin It seems like yesterday that you met JS Beals but your love has blossomed from a seed into a fully grown love plant," he said.
"Will you make JS Beals the happiest man in the world and marry him in real life?"
"We'll be eagerly awaiting your reply — eagerly."
Less than four hours after the initial tweet, Mr Beals announced via Twitter that his girlfriend had accepted his proposal.
Posting a message on the YouTube page where the video ran, Ms Hutt-Chamberlain also declared she had said yes.
"This is the best proposal that I could have imagined."
Mustafa became a viral video star after a bold and surreal commercial for Old Spice body wash debuted on US television during the Superbowl.
Entitled The Man Your Man Could Smell Like, the advertisement was given the Grand Prix at the Cannes Lions International Advertising Festival last month, the highest award for television commercials.
Mustafa, 36, became an actor at the end of his professional American football career in the late '90s.
