is there a way to make the shape of the area light round or ovoid?

I know it seems silly, but it would be nice to have for some of my shots. I'd like the option to be able to hide an area light in a source that's round.

I'm very new to the whole "area" light thing and superfly - so I'm sure it's a silly question.

thanks,

I came, I rendered, I'm still broke.
