Chances are you’re one of the millions of people who have fallen victim to the addictiveness and utter ridiculousness of Dubsmash. And if you’re not, you probably will be by the end of this page.

The app — which lets you lip-sync to songs, movie quotes, and more — has been consistently entertaining us since it launched last November. But what we really love is watching celebs try their hands (or mouths, in this case) at nailing the perfect dub.

We’ve rounded up 13 of the best celeb Dubsmash clips and ranked them by hilarity. Check it out:

Kate Upton and Justin Verlander

The supermodel and her baseball stud BF tackled the classic “Step Brothers” quote where Will Ferrell can’t understand if his interviewer’s name is Pam or Pan. Kate and Justin’s delivery is spot-on but lacks some spunk. More pizzazz, plz!

Khloe Kardashian and Kylie Jenner

Noticing a tag-team trend? That’s because partnering up on Dubsmash is always a hit, like when Khloe and Kylie reenacted this hilarious Vine. We especially love the way Kylie gives some major ‘tude. They love each other, ok bitch?

Hugh Jackman

Hugh does his best Professor Snape imitation with this “Harry Potter” line, nailing the slight snarl and lip quiver.

Lena Dunham and Jack Antonoff

Lena makes a strong case for why she should appear on “Lip Sync Battle” with this pitch-perfect rendition of Alanis Morisette’s vengeful “You Oughta Know.” And we love how Jack — shirtless and creepin’ behind her — chimes in for just a moment.

Adam Levine

Props to Adam for tackling one of Samuel L. Jackson’s most famous “Pulp Fiction” lines, but let’s admit it: he’s kinda too cute to pull off being that intimidating.

Sarah Hyland

The “Modern Family” star does a mean Honey Boo Boo impression and gets extra points for doing it WHILE getting all glammed up. She’s clearly a multitasking pro.

Carly Aquilino

Ugly faces will always win us over, especially intentional double chins. The “Girl Code” comedian’s take on Nicki Minaj’s manic “Anaconda” laugh is nothing short of perfection.

Kevin Hart

Kevin earns kudos by recording this in a public place, subjecting himself to strangers’ judgmental stares. Plus, his wild eyes perfectly mimic Robert Downey Jr.’s crazed “Tropic Thunder” character.

Josh Groban

Upon first viewing, we thought Josh missed the point of the app by forgetting to mouth the words. But then he threw us for a loop with his unique take on Mel Gibson’s “Braveheart” battle cry: “They may take our lives, but they’ll never take...OUR FREEDOM!” Bonus points for originality.

Rihanna and friends

How do we love this? Let us count the ways. There’s the flawless sunglasses, the way Rih Rih glances over her shades and stares down the camera as she imitates Seth Rogen in “Pineapple Express,” and the even more perfect way her friend chimes in at the end.

Dane Cook

Dane takes on one of the funniest and most cringe-worthy “Mean Girls” quotes ever with a totally straight face and impeccable delivery. NAILED IT.

Ashley Benson

The “Pretty Little Liars” star is a Dubsmash pro — look no further than this seriously LOL-worthy reenactment of a famous Vine. The way she throws her head back at the perfect moment and her delivery of the line “deez nuts” deserve an Oscar.

Camila Cabello

Try not to watch this more than once, we dare you. Earning the number one spot is Fifth Harmony’s Camila, whose impression of Donkey from “Shrek” is *everything.* The way she sassily flips her hair, stares you down, and spits the word “waffles” is truly captivating stuff. Please make more of these, Camila!
