"HAPPY BIRTHDAY to my love, my other half, my constant Inspiration and supporter. My best friend. My everything," Hudgens wrote in a message to Butler on Instagram in Aug. 2019. "@austinbutler ✨28 is going to be [fire emojis]."
After Butler landed the role of Elvis Presley in director Baz Luhrmann's upcoming biopic, Hudgens took to Instagram to celebrate. "I AMMMM OVERRRR THE F--KING MOOOOOOOOONNNNN," Hudgens wrote on Instagram in July. "I CANT WAIT SO PROUD OF MY HONEYYYYY!!!"
"It's hard for me to even put into words what that girl means to me," Butler told E! News in July at the premiere of Once Upon a Time in Hollywood. "I am so inspired by her everyday and I just love her to my core."
"The only one I have eyes for," Hudgens wrote of Butler on Instagram on Valentine's Day in 2019.
Back in 2018, Hudgens opened up to Women's Health about what makes her relationship with Butler work. "We both respect, trust and admire each other," she shared. "It's so solid now because I feel strong as an independent woman. I am very self-reliant, but it's nice to have a best friend you can share victories with as well as losses." Hudgens also added, "He inspires me more than anyone."
In a birthday tribute to his leading lady in 2015, Butler called Hudgens "the light of my life."
"The Ice man cometh and now he goneth looool @austinbutler first broadway show down and he shined every performance," Hudgens wrote in support of Butler in 2018. "So proud of my honey onto the next!"
