I really need your guy's help with trying to find a certain brand of dolls

[WaterDraw]

This is very urgent and I need your guys help now. I'm trying to remember what these dolls were that were based off of this book about this rock band and the lead singer is a princess I think and the members of the band are humanoid aliens. If it helps I think one of the dolls had blue and white hair. These are recent dolls, they were space and rock themed, and they were based on this book.
It is not Star Darlings
I know the books were sold at at least Toys "R" Us. I don't know if the dolls were TRU exclusive.
If anyone can help me, it'd be greatly appreciated. I have been trying to find what these dolls are for around 35 minutes now. the release date had to be somewhere around 2016-2018 if that also helps

Thank you everyone for your help.

You wouldn't happen to be talking about Spacepop would you?

Yes that is it! Thank you so much! I was worried I dreamt them up or something
