With that moustache, that looks like Dali.
Another SFW Josephine Baker that the painting reminds me of:
If you type in Josephine Baker + fez, it pulls up a Josephine Baker room at the Le Marrakech. I think that also should be indicative that it’s probably her.
I’m not seeing the likeness to Baker. The lips do look feminine, though.
I vote for Marcel Marceauas well. The lips and eyebrows look painted in the same style.
Just doesn’t look caucasian to me.
I expect you’re right about that—but the artist’s technique, there, didn’t really work out. The end result doesn’t look like facial creases, much. 
Belgian singer Stromae.
OMG!!
My daughter just told me about Stromae a few months ago - she loves his music. When I first saw your thread yesterday, that’s exactly who I thought it was, but I wasn’t completely convinced. I wonder, however, if Stromae’s pose is simply a representation of the real person in that painting.
