In honor of his mother’s birthday, Liam Hemsworth posted a throwback picture of his parents on Instagram. In the post, the actor wished his “beautiful mum” a happy birthday, while also questioning what it was that his dad was doing in the picture. However, no matter what it is that his father was doing in the picture, which looks like an image from their wedding, Liam Hemsworth wanted his mother to know how much he loves her, while also letting her know that she is the “best.” He then finishes the post with a message to his father in which he simply says, “dad you’re an idiot.”
