We’ve been fans of Jennifer Lopez for a pretty long time now, but TBH, we don’t actually know all that much about her kids. As it turns out, though, they’re actually super funny — and they’ve grow up super fast to become sassy pre-teens. 10-year-old twins Max and Emme recently got all dressed up for Halloween, and they were clearly feeling themselves in their costumes. The celebrity kids were giving their mom all the attitude that we’ve come to expect from the star herself.

Though Emme was dressed up as a “glamorous cow” and Max was dressed up as the Joker from The Lego Batman Movie, it’s clear both kids are actually total jokers. “I could give people the middle finger and they won’t know it,” J.Lo’s son says hilariously, showing off his lego hands. “I’m doing it right now!” Emme, who’s got her hands in the pockets of her spotted onesie, is also smiling a little smugly until her mom says, “Both of you are!” Check it out.

“You know what? I taught you better,” the pop superstar scolds, but it’s clear she also thinks the whole thing is pretty funny. It’s even funnier when Emme admits that she did teach them better — and then proceeds to show off some epic dance moves. Guess mom taught her that, too! And it’s clear where the two got their sense of humor from. After J.Lo shared the video, she captioned the photo, “Max is such a joker and Emme’s really milking this Halloween thing.” She also added the hashtags #itaughtyoubetter, #clowningaround, #udderlyadorable, and #shesgotMOOves. Our favorite one, though, is #milkshake. Too funny.

But seriously, these kids are cracking us up. J.Lo should let us know if they ever need a babysitter or something, because we’d be down to hang out with them all day long. But the scary part is that they’re almost too old to need a baby sitter. It seems like just yesterday the singer’s kids were tiny tots, and now they’re almost teens. Earlier this month, their mom posted a throwback photo with them, captioning it, “Me and my lil coconuts,” and our hearts pretty much melted. It won’t be long until they’re all grown up, but in the meantime, we can’t wait to see what they get up to next.
