Love is always in the air for Hollywood's hottest A-listers, but this year, fans were shocked to learn about the wild and unexpected hookups that went on between the industry's sexiest stars. From Hailey Baldwin and Justin Bieber's secret wedding to Ben Affleck's bizarre romance with Playboy model Shauna Sexton, flirty celebs sure did not disappoint. Click through RadarOnline.com's gallery to take a look back at 2018's most shocking celebrity hookups.

Hailey Baldwin, 22, and Justin Bieber, 24, stunned fans, friends and even their own family members when they rekindled their romance earlier this year and tied the knot weeks later! While the "Sorry" singer had a years-long on-and-off relationship with Selena Gomez, he took to Instagram this July to confess his undying love for longtime BFF Baldwin and come clean about their quickie engagement. Then, this Thanksgiving, the hunk admitted he was finally a "married man!" Plus, Baldwin changed her last name to Bieber in her Instagram bio — so it's definitely official.

Ariana Grande's romance with Pete Davidson, 25, may have failed, but it was a total fairytale while it lasted! This May, days after news of Grande's split from Mac Miller broke, the pop diva was spotted at a Saturday Night Live performance where the comedian was present. Soon, Davidson got a series of tattoos dedicated to the "Dangerous Woman" and the two finally went public with their romance. About two weeks into their relationship, Davidson proposed to Grande, 25, and she said yes! The love birds moved in together and got a pet pig, but in the months that followed, tragedy struck. Grande's ex, Mac Miller died of an accidental overdose, causing the beauty to fall into a downward spiral and call it quits with her funnyman hunk. Now, he's moved back in with his momma, and she's said, "thank u, next."

Priyanka Chopra, 36, and Nick Jonas's romance started about two years ago, when the two bumped into each other at a Hollywood bash. At the time, Jonas, 26, texted Chopra, the two went on an awkward date, and they didn't speak for an entire year after that. Then, in 2017, the two bumped into each other again at the Met Gala, and went on a proper date. It was then that the singer realized he was going to marry Chopra. The two got engaged in July and married in December — in the most lavish Indian-American ceremony ever! Now, the actress' Instagram bio reads "Priyanka Chopra Jonas." 

Meghan Markle, 37, and Prince Harry's romance will go down in history as one of the biggest royal scandals ever. But for the love birds, it's simply a dream come true. This May 19, the former Suits actress married the 34-year-old hunk in a lavish ceremony at Windsor Castle. Soon she was named Duchess of Sussex, and just weeks later, announced she was carrying their first child!

Chris Pratt, 39, and Katherine Schwarzenegger can't get enough of each other! It's been over a year since the Passengers actor called it quits with wife-of-nine-years Anna Faris, 42, and yet, fans still feel the sting of their nasty split. But the hunk and his ex have clearly moved on. For a few months now, Pratt has been spotted hanging out with his hot new girlfriend, and they seem to be getting serious! Earlier this month, he was even seen having lunch with Schwarzenegger, 28, and her famous dad. And later, he was caught enjoying a trip to Disneyland with her and his young son!

But Pratt isn't the only one who's introduced his new love to 6-year-old Jack. Overboard star Anna Faris has also welcomed her new hunk, Michael Barrett, 48, into the family. They two are often seen out on intimate dates — both solo and with the actress' kid!

Kourtney Kardashian, 39, is one hot cougar! After breakup with boytoy Younes Bendjima, 25, the Keeping Up With the Kardashians star moved on with a string of hot men: most recently, barely-legal Luka Sabbat! The 21-year-old male model has been hanging out with the mom-of-three star for a few months now. And while Kardashian's famous sisters think it's gross that she's dating someone so young, she's just living her best life!

Kaley Cuoco, 33, is a married woman! This June — just two years after finalizing her nasty divorce from ex Ryan Sweeting — the Big Bang Theory actress married handsome equestrian Karl Cook, 27. "Happy ever forever" the bombshell captioned a sweet photo of her and Cook from their emotional wedding day.

Amy Schumer, 37, shocked fans when she announced she'd secretly said "I do" to hot chef Chris Fischer, 38. After just weeks of dating the two married in a gorgeous and very intimate tropical ceremony this February. Guests included the comedian and the hunk's close friends and family members — and also Jennifer Lawrence. Schumer and Fischer did not announce their engagement when it happened, but after news of their nuptial broke, the star shared a series of photos of their big day on Instagram, simply writing "Yup."

Demi Lovato, 26, is celebrating life with her hot new boyfriend after escaping death this July when she suffered from a horrific drug overdose. Now that she's attended rehab and made a vow to stay sober, the "Tell Me You Love Me" singer is moving on with Henri Levy, 27, another recovering addict. The handsome fashion designer has been spotted out on dates with Lovato several times this month, and while the two look happy as ever, it seems the star's mom is not so supportive of their relationship. A source told RadarOnline.com that Dianna Hart believes newly-sober Levy is "not a good influence" for Lovato, as he still lives a hard-partying lifestyle and that is the last things the beauty needs!

Ben Affleck, 46, went on a bit of a dating binge after getting dumped by longtime girlfriend Lindsay Shookus, 38, earlier this year. The actor — who has long struggled with substance abuse — fell into a pit of depression which resulted in a nasty boozy relapse and yet another stint in rehab. Days after the SNL producer moved out of the mansion they shared, Affleck was seen parading around town with Playboy model Shauna Sexton, 22. And while the two were hot and heavy for a while, that wild romance ended very quickly — and not so amicably.

Now that their divorce is finalized, Affleck's ex, Jennifer Garner, 46, has moved on with sexy businessman John Miller. Insiders say she avoided dating until after their legal drama was over, but now she seems to be very happy with her new man. And even though it's been three years since she and Affleck separated, sources close to the stars say the actor is "devastated" that Garner may have found her next husband! Apparently, he was hoping she would stay single forever! Which celebrity hookup was the most shocking of 2018? Let us know your thoughts below.
