Simu Liu is wishing his girlfriend Allison Hsu a happy birthday!

On Tuesday, Liu, 34, shared a photo of himself and Hsu cuddled up together on Instagram, where he wrote in a caption: "There’s simply nothing better than holding your hand."

"happy birthday to the girl who truly does it all. she inspires me in her passion for music (well… one musician specifically)," the Barbie actor wrote, in an apparent reference to the couple's trip to Taylor Swift's concert in Seattle on July 23. Liu has also dabbled in singing himself.

The Marvel star went on to write that Hsu, who he has been dating since late 2022, "teaches me how to balance a busy and chaotic schedule with grace, and touches me in how she cares for each and every person in her life."

"most importantly, she shows me that the people we love are always worth fighting for," he added in his caption. "whether we’re on another crazy trip to god-knows-where for who-knows-what, or just binging our way through 'friends' at home, there’s simply nothing better than holding your hand."

Liu previously told PEOPLE at Barbie's Los Angeles premiere in July that he and Hsu "fight to spend time together."

"We've got a packed summer," the actor said at the time. "I mean, [the] schedule's always packed and it's always, you know, it's just hard for anybody who travels a lot to fight for time together and make sure you're taking enough time to be present with each other and to kind of block out everything that everybody wants and to just kind of be, to have a moment that’s just ours."
