North's been to Disneyland a bunch with her famous parents, and other family members, over the years -- but this is the first time she's been with stepmom Bianca -- instead of Kim Kardashian -- as far as we've seen.
TMZ obtained photos of the trio making their way through the huge Disneyland holiday crowds with a personal Disney tour guide, of course, and some security in tow.
Kanye and Bianca have been married about a year now, and all evidence points to his kids totally warming up to her.
After riding the Haunted Mansion, we're told the West trio hoofed it over to nearby Frontier Land for more fun.
As you can see, Kanye is covering up in a black hoodie, and we're told the group went largely unnoticed -- which, as you'd expect, never happens when Kim's there. Interestingly, Bianca was rocking one of her standard bodysuits, but a much more conservative, non-see-through, family-friendly one.
Kanye and Bianca have been all over the world this year -- Japan, all over Europe and then Dubai ... where, earlier this week, Kanye unveiled his new album, "Vultures."
North has a verse on the record, so you could view the trip to Anaheim as a celebration of her rap debut. Miss Westie loves her some Disneyland!
