TREE = Anna Gasteyer (from SNL, etc.)
FLAMINGO = Jackie Aina (YouTuber)
BUTTERFLY = Ginger Spice (Spice Girls)
PENGUIN = Not enough to go on yet, haven't really seen them perform, etc.
LEOPARD = Dennis Rodman (though my daughter's guess is Billy Porter)
ROTTWEILLER = Chris Daughtry
FLOWER = Not enough yet, as hasn't performed, but from clues, Mayim Bialik (Blossom, Big Bang Theory)
THINGAMAJIG = Victor Oladipo
PANDA = This one was revealed last night, Leila Ali. (I totally could not guess this one, so I'm already one incorrect)
BLACK WIDOW = Just a guess so far, Vivica A. Fox, though could be any female singer off the Empire TV show....
LADYBUG = Kelly Osbourne
EGG = Was revealed as Johnny Weir (Olympic skater)
ICE CREAM = Was revealed to be Ninja (YouTuber), I had no idea, but my daughter guessed it.
