Mr Owens was pictured in a Trader Joes, a chain of grocery stores in the US, while he was working there to make ends meet.
The household name said he was “devastated” during an interview with Good Morning America, saying he had been shamed by media outlets for his latest job.
Amid the criticism he received, however, Mr Owens said he was also sent several messages of support, which helped.

He said: “The period of devastation was so short because so shortly after that, the responses my wife and I started to read [from] literally all over the world… the shame part didn’t last very long.
“It hurt, but then, it’s amazing.”
On the Cosby Show, Mr Owens played Elvin Tibideaux, the husband of one of the Huxtable daughters, Sandra.
Since leaving the successful sitcom, Mr Owens admitted he had not had an acting job that lasted longer than ten weeks.
To make ends meet, the actor said he had been working in Trader Joes for 15 months, before photos of him at work appeared on Fox News and the Daily Mail.
He said fans of the show still recognise him, and were usually respectful.
He said: “People recognised me every day and they were very, very cool about it.”
He added: “No one should feel sorry for me, I’ve had a great life and I’ve had a great career.”
