Prince Harry and Meghan Markle
Alex Rodriguez and Jennifer Lopez
This was a romance we didn't see coming, but we love it! J.Lo and A-Rod shocked the world when they were spotted hanging out together in February. It wasn't long before the two made it official, confirming their relationship in multiple interviews, and they have been seemingly inseparable ever since. From date nights in Miami to relaxing getaways in the Bahamas, the two have showed plenty of PDA this year, all over the world.
Chrissy Teigen and John Legend
These two topped our list last year, and we couldn't help ourselves from including them again! The hilarious duo celebrated their fourth wedding anniversary this year with a seriously sexy date night. Two months later, Teigen and Legend revealed in an Instagram video that they are expecting their second child together through in vitro fertilization.
Khloe Kardashian and Tristan Thompson
It was revealed during an episode of Keeping Up With the Kardashians that the reality star actually met the NBA player on a blind date. Romance rumors ignited last September when the two were spotted packing on the PDA in Miami. Since then, they haven't been shy about their relationship, kissing in public and tagging each other in posts on social media, and the two have recently taken their love to the next level! In October, a source told ET that Kardashian and Thompson are expecting a baby boy together, one month after we confirmed that the Revenge Body star was pregnant.
Blake Shelton and Gwen Stefani
These two make it feel like Christmas! Yep, the country crooner and No Doubt rocker are still going strong after passing their two-year mark as a couple in November. While Stefani's three boys, Kingston, 11, Zuma, 9, and Apollo, 3, have seemingly been big fans of Shelton since the beginning, he's spent a lot more time with them in 2017, including trips to Disneyland and his home state of Oklahoma, and featuring them in his "I'll Name the Dogs" music video. A source close to the couple told ET in October that Shelton is hoping for a few kids of his own… with Stefani, of course.
Selena Gomez and Justin Bieber
Jelena forever! Shortly after calling it quits from The Weeknd in October, Gomez was spotted spending time with her on-again, off-again ex-boyfriend, Justin Bieber. Since then, the two have been photographed riding bikes together, attending church services, cozying up during an intimate date nightin Los Angeles and packing on the PDA.
Brooks Laich and Julianne Hough
Cardi B and Offset
The hip-hop world couldn't keep their cool when they discovered the "Bodak Yellow" singer and Migos rapper, who reportedly first locked eyes in February, reignited their romance in October following a brief breakup. In one of the most exciting onstage moments of 2017, Offset adorably proposed to Cardi B while the two were performing together at Power 99's Powerhouse in Philadelphia, Pennsylvania, in October.
Jenny Slate and Chris Evans
Life is pretty great when you're dating a superhero -- just ask Jenny Slate! Fans were beyond excited when the Parks and Recreation actress and Captain America: Civil War star began dating in May 2016 and devastated when they briefly broke up in January of this year. But all is well now -- the two are officially back together! Slate teased their reconciliation via Twitter in early November, writing, "My boyfriend does many dreamy & generous things but number 1 in my mind right now is how he celebrates my new turtlenecks/let’s me show him my online shopping spoils & cheers me on."
Val Chmerkovskiy and Jenna Johnson
Who doesn't love a good Dancing With the Stars love story? The professional dancers -- who dated in 2016 but briefly called it quits -- reignited their romance in June, making it official by sharing pics of each other during a romantic European vacation. Since getting back together, the adorable duo has been posting plenty of PDA-filled pics via social media, but nothing has warmed our hearts more than the time they shared the stage for a performance during DWTS' season 25 finale.
Russell Wilson and Ciara
It's been an amazing 2017 for this power couple, who welcomed their first child together, daughter Sienna, in April. Ciara, who is also mother to 3-year-old son Future, said "I do" to the NFL pro last July in Cheshire, England, and it's seemingly been a fairy tale romance since day one for these lovebirds!

He's amazing."

The two tied the knot in November in a stunning Beauty and the Beast-themed ceremony in New Orleans, Louisiana, surrounded by their closest family and friends.

The wedding came just two months after Williams and Ohanian welcomed their first child together, daughter Alexis.
Samira Wiley and Lauren Morelli
It's been an exciting 2017 for the Orange Is the New Black star, who married show writer Lauren Morelli in Palm Springs, California, in March, less than a year after announcing their engagement. "It's great," Wiley said of married life while speaking to ET in September. "We fell in love and the love is real, and we're still so happy. I wouldn't be able to be here without her support. My professional journey really started with Lauren, working side by side, and now having her in the role that she is, being my wonderful wife, she's helped me through every single stage."
Natalia Dyer and Charlie Heaton
Although these two have yet to confirm their relationship on their own, we can't get enough of how upside down these Stranger Things co-stars seem to be for each other. They first sparked romance rumors in January and were most recently spotted in November, sharing a steamy smooch in London, England, just a few days after holding hands in Paris, France.
