Liam Hemsworth and his dog make one ridiculously cute duo [2]. On Tuesday, the handsome actor took to social media to share a fun photo with his pup. Liam did his best impression of his dog, eyes wide and tongue out, joking, "It's hot..." Of course, this is just one of many gems he's shared since joining Instagram a few weeks ago. First, Liam posted a photo with "the most beautiful girl in the world," [3] Miss Piggy, and then he had followers doing a double take when he posted a pantsless picture of himself [4] at the Toronto Film Festival. Can't get enough of Liam? Check out the best snaps of the Hemsworth brothers [5] through the years, including their sweet red carpet appearance [6] this Summer.
