Liam Hemsworth and Miley Cyrus don't show PDA very often, but when they do, it's freaking adorable. On Monday night, Liam shared a sweet Instagram photo of Miley giving him a kiss on the cheek using a cartoon filter. "Life is way cooler in cartoon," he captioned the shot. As if that wasn't cute enough, Miley's mom, Tish, also left a comment on the snap [2], writing, "Love my sweet family soooo much!" Miley and Liam resumed their engagement [3] back in January, and even though they're not married yet, it's clear that they're already one big happy family [4].
