Sister, sister! Maddie Ziegler and her sister Mackenzie Ziegler look a lot alike, but there is one feature the former Dance Mom's star would love to steal from her younger sister. "I would definitely say her lips. I know that's kind of weird, but she has very juicy and scrumptious lips and a lot of people pay money to get those lips," Maddie said during a Q&A with fans on her YouTube channel.

"So she's just blessed with the best, you know? No, but honestly, I just wish I had Mackenzie's face just because she's perfect," Maddie added. "I love her to death and I would love to look like her when I'm older."

It's not incredibly shocking that Maddie would want bigger lips, either. A plump pout is totally in, thanks to Kylie Jenner.

And, oddly enough, Mackenzie's lips made an appearance in the YouTube video! She showed up halfway through the Q&A session and totally knew Maddie said "lips" as her desired feature. "Not my nose, that's for sure," the younger sister joked.

Between the giggling and hanging out on camera, fans loved seeing the duo together. "Oh my gosh, I wish my sister was like that with me," one person wrote in the comments. "You two have the best relationship, never give it up!" Another said, "And I think (no, I'm sure..that) you and Kenzie are like the perfect pair of sisters!!"

The world was introduced to the Ziegler sisters way back in 2011 when they danced for Abby Lee Miller at the Abby Lee Dance Company in Pittsburgh, PA. Since then, they have quit the show and grown up in front of our eyes. While Maddie usually keeps quiet about her failed relationship with Abby and her experience on Dance Moms, Mackenzie isn't so shy.

"I started to regret not being a 'real kid' with a real life," Mackenzie wrote in a tell-all book about her time on the show. "I felt like I had no childhood, and it made me sad and angry… I thought everyone was constantly judging me, watching each move and tearing it apart, nitpicking everything I did and laughing at me behind my back. The competitive dance world and reality TV can get a little crazy."
