Happy birthday, Liam!
Aussie star Liam Hemsworth got some serious love from his lady love Miley Cyrus on his 28th birthday.
The rockin' singer posted a sweet Instagram Story as well as an Instagram sharing her heart.
The fun-loving performer shared a post that had several photos of the longtime couple with the caption, "Happiest birthday to my very best friend on the entire planet! I [heart emoji] u!"
On her Instagram Story, the "Malibu" singer, who is in Australia with her hunky man, posted a colorful image that said, "Today is VERY special because it's someone VERY special's birthday!"
The wild child decorated the images in full Miley glory, complete with rainbow hearts, party hats, colorful balloons and a pink birthday cake.
Earlier in the week, E! News reported that the former Disney darling was having a blast with Liam and his fam Down Under.
"Miley has spent the last two weeks in Australia enjoying the summer weather with the Hemsworth family," a source told E! News. "They rang in the New Year at Chris Hemsworth's compound at a Burning Man themed party with Matt Damon and several friends. Everyone had elaborate costumes and went all out for it."
"Miley has a lot of fun with the Hemsworths and fits in very well," the insider shared. "The whole trip has been a very laid back beach vacation with lots of lunches and dinners out and just bumming around town. Miley really loves her time in Australia and it feels like a second home to her. She blends in with the locals and the casual beach vibe. It's similar to her life with Liam in Malibu that she cherishes so much."
