"Secrets out!! So happy for you guys! Been a long time comin'," Brandi Cyrus wrote on a screenshot of the couple's sweet wedding photo
Miley Cyrus and Liam Hemsworth’s love can’t be tamed.
The singer’s older sister Brandi — who was in attendance at the newlyweds’ surprise wedding on Sunday — congratulated the stars on their new union on her social media account.
The “Your Favorite Thing” podcast host, 31, posted to Instagram on Wednesday to share her excitement for the pair, who gave family and friends an early Christmas present when they secretly tied the knot.
“Secrets out!! So happy for you guys! Been a long time comin’,” Brandi wrote on a screenshot of the couple’s sweet wedding photo.
“Love you both,” she added at the bottom of the post.
In one snap, she and her groom, 28, are all dressed up in their wedding best — a floor-length white gown for her and black tux for him — as they share a smooch. And in two other photos, the actor has his arms wrapped around Miley’s waist as they share a quiet moment together in front of what appears to be an altar adorned with roses and baby’s breath.
Even in the comments of her posts, the singer couldn’t contain her excitement about the big day. When a fan told Cyrus on Instagram, “Congratulations you married the hottest man in Hollywood!!!!,” Cyrus enthusiastically agreed. “I knooooowwwww right” she wrote, as seen by popular fan site Comments by Celebs.
Photos and video posted to the Instagram story of the couple’s surfer friend Conrad Jack Carr on Sunday showed Hemsworth and his brothers Chris and Luke doing a “shotski,” with Mr. and Mrs. balloons in the background. Another photo showed the newlyweds in front of cake and cupcakes, with the singer’s mother Tish in the frame.
Miley and the Hunger Games actor’s private wedding comes after a rocky, on-again, off-again relationship between the Last Song costars. She and the Australian actor dated for years before he proposed in 2012, but the two ended their engagement and broke up a year later.

On her last album, Miley sang about finding love again with Hemsworth. Sings the star on her hit song “Malibu”: “I’d spend the rest of my life just standing here talking / You would explain the current, as I just smile / Hoping I just stay the same and nothing will change / And it’ll be us, just for a while.”
