Miley Cyrus and Liam Hemsworth Embrace the '80s Theme at Luke Hemsworth's Birthday Party

If Luke Hemsworth could turn back time, he'd turn it back to the '80s.
So, to celebrate his 36th birthday over the weekend, the Westworld star decided to throw an '80s-themed birthday party. Guests including Laural Barrett, Mark Furze, Miley Cyrus, Eric Haskell, Jaime Haskell, Katie Jensen, Lisa Oberwager, Jen Rossi and Courtney Tyler Seashols—plus brother Liam Hemsworth and wife Samantha Hemsworth—got into the spirit, wearing colorful costumes inspired by Luke's decade of birth. The actor even dressed up as comic book and cartoon character He-Man. As he joked on Instagram, "Fabulous secret powers were revealed to me the day I held aloft my magic sword and said 'by the power of greyskull!'"
Luke took the '80s theme very seriously. His birthday cake was modeled after Pac-Man and Rubik's Cube, and his wife shared a number of Polaroid pictures with her Instagram followers.

A wigged Liam wore a yellow tank top and red shorts, accessorizing with sunglasses, a gold chain and a pink sweatband. Miley, meanwhile, paired a Madonna T-shirt with a leather skirt.
Many attendees shared pictures from the California party via Instagram.
"Like totally gnarly dude, the 80s are back! #80sparty," Samantha posted, adding that they were "#missingafewpeople." One of those people was Zac Efron, who was in New York. "We missed you!!" Samantha wrote in her photo caption. "You better be in town for the next party!"

Luke's brother Chris Hemsworth was also M.I.A., as he was in their native Australia.

Needless to say, the party was one they won't soon forget. "Halloween just keeps on giving this year," Laural wrote on Instagram, later adding, "Happy birthday @hemsworthluke ya legend!!"
