A spark ignites between the two when they film the Nicholas Sparks movie together. Like their onscreen characters, the two quickly fall for each other with the beach as the backdrop.
The co-stars make their first public appearance as a couple at the Elton John AIDS Foundation's 2010 Oscars after party.
After nearly three years together, the duo decide to take their relationship to the next level. "I'm so happy to be engaged and look forward to a life of happiness with Liam," the bride-to-be tells People in June 2012.
In what would become a theme in their relationship, the actors call it quits in fall 2013, with sources telling E! News that the breakup was "Miley's decision, after coming to grips with Liam being what she believed was less than faithful to her."
Just one day after it was confirmed that Liam and Miley had called off their 15-month engagement, he was spotted kissing Mexican actress-singer Eiza González.
Miley releases this tearjerker of a song, which was inspired by what she said were the "motherf--kers" that broke her heart, "particularly one." The music video, which shows her sitting and swinging on wrecking ball naked, inspired many memes.
Miley begins to cozy up with Patrick Schwarzenegger. The two look happy as can be while on fun-filled dates at Disneyland in March 2015, but alas, all things must come to an end. It is reported a month later that the pair has broken up because of Patrick's alleged infidelity.
Miley and Liam remain close despite their public split...so close that she helps him adopt a dog.
Following their rough patch, Miley and Liam reignite their romance at the Falls Music Festival in Byron Bay in the actor's native Australia over the 2016 New Year's holiday. Witnesses report that the couple showed some heavy PDA.
Miley and his family begin to spend more and more time together, so it is no surprise that she and Elsa Pataky (Chris Hemsworth's wife) chose to get matching tattoos together in April 2016.
In October 2016, the "Wrecking Ball" singer goes on the Ellen DeGeneres Show, wearing her engagement ring.
The two are absolutely beaming in an adorable shot of the pair in their holiday best.
In her 2017 song, Miley gushes over the love she shares with her beau. "We had to re-fall for each other," she told Billboard.
Once again, rumors of a breakup began to swirl around the couple, but they put those whispers to rest with a hilarious video in their car.
Liam just can't pranking his fiancée! Fans are loving the pair's dynamic.
in November 2018, a massive wildfire destroyed Miley and Liam’s Malibu house and hundreds of other homes near Los Angeles. She was out of town, while Liam was home and managed to escape with all their pets. Miley told Howard Stern, "He got a lot of action for saving the animals."
Fans are positive the two had gotten married just before Christmas after a friend posts images of what appeared to be their wedding, held inside a home.
Just after Christmas, Miley appears to confirm her and Liam's marriage with a few photos, including one showing her in a white wedding dress by Vivienne Westwood and him in a black suit."
The Mr. and Mrs. make their first official appearance since tying the knot at the G'Day USA Gala in Los Angeles. "Thank you to my beautiful wife," the Isn't It Romantic actor gushes over Cyrus in his acceptance speech. "You are a sweet, sweet angel."
The lovebirds get all dressed up for their highly-anticipated appearance at the Met Gala in New York City.
In June 2019, the pop songstress marks her and Liam's anniversary with a little bit of shade to their haters. "Happy 10 year anniversary my love," Cyrus wrote alongside an article that addresses the split speculation. "Good to see everyone is as dumb as they were in 2009! Some things never change .... & I hope the way you feel about me is one of them. Yours truly."
In August, a rep for Cyrus tells E! News in a statement, "Liam and Miley have agreed to separate at this time. Ever evolving, changing as partners and individuals, they have decided this is what's best while they both focus on themselves and careers. They still remain dedicated parents to all of their animals they share while lovingly taking this time apart. Please respect their process and privacy."
