I love rexes! I bred what I thought were 2 rexes and got 6 little hairless things... But the other 5 were the most fluffy curly little rexes I have seen so far, that is until this thread and that pic of your little Suzy Q!
That face marking is a recessive blaze, aka "jester"!
Lightening blazes can be Recessive or Dominate, hopefully in this case it's a recessive blaze.
Jester?
The one on top doesn't look like a normal rex...velveteen, maybe?
Rex's and velveteen's are pretty much the same gene and are compatible with each other.
It definitely could be a velveteen although that genetic is still not super common.
