Kourtney Kardashian and Travis Barker, Megan Fox and Machine Gun Kelly, and Harry Styles and Olivia Wilde were just some of the couples who couldn't keep their love to themselves in 2021.
So which celeb couples just couldn't keep their hands to themselves this year? Look back on all of the PDA that went down in 2021. (Don't worry, it's all SFW. Mostly!)
Kourtney Kardashian and Travis Barker
The world was Kravis' stage in 2021.
After revealing their relationship on Instagram in February, the Keeping Up With the Kardashians star and her rocker beau were not shy about expressing their love for one another. They frenched at a UFC fight. They couldn't keep their hands off each other in the studio. They kept it PG and held hands at Disneyland. They went on a dreamy trip to the desert.
And their PDA was taken to the next level when the Blink-182 drummer popped the question on the beach in October. Following their swoon-worthy engagement, the pair went on a romantic getaway to Mexico and Kourt straddled Travis at her BFF Simon Huck's wedding before he sucked her toes in an Instagram pic in December. Now, if that doesn't say true love...

Machine Gun Kelly and Megan Fox
If their BFFs Kourt and Travis are the first couple of celebrity PDA, the self-proclaimed twin flames are their VPs. Whether they were touching tongues on the red carpet, straddling each other during concerts or posing for steamy magazine photoshoots, these two just couldn't get enough of each other. Like, he wears her blood on a chain around his neck!

Ben Affleck and Jennifer Lopez
How lucky are we to be witnessing Bennifer 2.0? Since the pair were first photographed together for the first time in over 15 years when they vacationed in Montana in early May 2021, we've eaten up every affectionate public appearance the reunited couple have made. Plus, we will forever be grateful for their steamy recreation of their infamous "Jenny From the Block" music video.
Channing Tatum and Zoe Kravitz
Never have we been so jealous of a bike. And yet...it proved to be the iconic accessory in the first pics taken of Channing and Zoe in NYC, with The Batman star holding her beau close. The new It couple then attended the Met Gala, though they didn't pose together on the carpet, and were spotted hand-in-hand in October.
Phoebe Dynevor and Pete Davidson
What would've Lady Whistledown have written about the Bridgerton breakout star's fling with the Saturday Night Live star? Before breaking up after a four-month romance, the duo made one public appearance together when they were photographed getting cozy at Wimbledon.

Kim Kardashian and Pete Davidson
Where were you on Nov. 17? Don't worry, we know the answer: You were losing your mind over the first official photos of Kim and Pete holding hands, confirming their relationship with—what else?—a trip to Hot Dog on a Stick. If that didn't seal the deal, the fact that the SKIMS founder then willingly visited Staten Island several times definitely did.

Harry Styles and Olivia Wilde
We were on a "Watermelon Sugar" high after we saw the photos from the Grammy winner and the Don't Worry Darling director's romantic and sun-soaked getaway to Italy this summer. Ciao, jealousy!

All hail the first couple of the MCU! The Spider-Man: No Way Home stars' had the Internet in a full-blown meltdown when photos of them kissing in a car were taken in July. Ever since, their rekindled romance, which has included many fanboy moments from Tom on Instagram, has ensnared us all in its web.

What better way to celebrate an engagement than with a kiss posted on Instagram? With a taste of his lips she's on a ride to the altar!
Chrishell Stause and Jason Oppenheim
The Selling Sunset co-stars' romance may have been short-lived, but their Instagram debut as a couple will have a long-term lease in our hearts.

After making their romance IG official in January, the Creed star and Steve Harvey's daughter gifted the world with cute updates on their relationship throughout the year, including an inside look at their affectionate first anniversary celebration.

Though this couple is usually quite private, Kendall isn't afraid to reward her man when he scores hoops, or whatever it is they do during basketball, when she sits courtside at a Phoenix Suns game.

She screams, he screams, we all screamed "New couple alert!" when the Maid actress and Taylor Swift's go-to producer were spotted on an ice cream date in New York City.

Nothing says "We're back together, baby!" than smooching on a red carpet, which is exactly what the reconciled couple did in October.
