From the moment Disney Channel announced its new show Andi Mack, you knew it was going to be different from anything you've seen on the network in a long time. Not only is it created by the genius behind Lizzie McGuire, Terri Minsky, but it's also the first DC show to star a majority Asian-American family.

Apart from those amazing reasons to watch the show, there's a plot twist in Andi Mack that's actually going to shock you.

I know what you're thinking. With the story following a sheltered 12-year-old whose older, cooler sister returns home on her 13th birthday and reveals a secret that changes her life forever, the twist is probably something totally Disney Channel. Like her dad is a rock star or the Macks are actually a bunch of aliens from Mars and they have to return to their home planet now that Andi's 13.

Well, this revelation is waaaaay more shocking. The secret revealed right at the end of the pilot episode is so huge, and so unexpected, you'll wonder if Andi Mack is really a Disney Channel show. And we've got the exclusive scoop on it right here.

*Stop reading here if you don't want to be spoiled.*

Okay, so ready for this? It turns out, Andi's sister Bex... is actually her MOTHER.

Just let that sink in... Woah.

It's shocking because it's so... real, and a seriously mature subject for a DC show.

According to Minsky, that's exactly what Disney Channel was looking for when they came to her for a new show — something different. But when she pitched them Andi Mack, a story she'd conceptualized after reading about the famous actor Jack Nicholsonfinding out his sister was actually his mother, she didn't think for a second they'd go for it.

"When The Disney Channel called to say 'Listen, we're thinking we need to come up with something different and you did it for us before [with], do you have anything?' I was kind of thinking, well, yeah. But, in like a million years, I really didn't expect them to go for it," Terri told Seventeen.com.

But they did and while the show's creator confirms the show won't be super scandalous, she was impressed that the network was so open to this more grown-up storyline. "I'm so glad that they went for it," she continued. "Obviously I didn't come to them with drugs and alcohol problems, but every single thing we've wanted to do — they've been like, okay, so it's been a great experience."

And that risk has totally paid off. Andi Mack has the exact same real-life feel you loved about Lizzie McGuire, only with this crazy twist that's going to add a refreshing emotional layer to the show. Trust me, watching Bex reveal to Andi that she's actually her mother is such a touching, emotional moment, you'll actually cry.
