Kim Kardashian and all of her children are showing just how much they love and support Daddy ... they're back in Atlanta for Kanye West's encore "Donda" album release.

Kim and their kids -- North, Saint, Chicago and Psalm -- are on the East Coast yet again to attend Ye's second event at Mercedes-Benz Stadium in 2 weeks in anticipation of the release of his 10th studio album ... scheduled for Friday.

Kim and the kids are dressed head to toe in Balenciaga, which sorta makes sense ... the creative director behind the event is the head of Balenciaga.

We're told some family friends are also with Kim -- including KKW's Chief Marketing Officer Tracy Romulus and her kids -- to celebrate the rapper's momentous occasion.

Worth noting -- our sources say this is not some sign that Kim and Kanye are getting back together ... the divorce is still happening, but the family support remains strong.

As we first told you ... Kim and the family were also in attendance on July 22 when Kanye first debuted "Donda" ahead of its initial July 23 release date. It never came out, though ... thus his need for round 2.

Our sources say the plan is for Kayne to put a new twist on the second album release event ... which looks like it may involve transforming into a supervillain.

Then again, as Khloe recently told us ... only Kanye truly knows what's in store.
