Charlie Sheen was seen back at work with his new but anonymous girlfriend.

X17Online.com reports that Sheen couldn't keep his hands off the young blonde, but when asked what his girlfriend's name was, he replied, "None of your f**king business."

During an interview with 'The Dan Patrick Show' last week, Sheen revealed he has a new woman in his life, but he declined to reveal her identity. He said he is "100 percent" in love.

Sheen definitely has a lot of affection for the woman and was not shy about kissing the blonde between takes.
