Comic ____ DeGeneres (5)
I believe the answer is:
ellen
'comic degeneres' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ellen that I've seen before include "Woman" , "the Lady of the Lake" , "- Terry, Eng. actress" , "MacArthur, round-the-world yachtswoman" , "It could be Terry" .)
