Is it just us or do Miley Cyrus [1] and Liam Hemsworth get cuter every day? On Thursday, the "Malibu" [2] singer celebrated National Kissing Day by posting an adorable throwback of the two filming their 2010 movie, The Last Song. "Happy #InternationalKissingDay! 💋💋💋," she wrote alongside a photo of them making out in the ocean [3]. "Our first smooch 8 years ago! ❤️❤️❤️." Aww! It's pretty fitting that they met on the set of a Nicholas Sparks adaptation since playing love interests "sparked" their real-life romance [4]. Even though they took a brief break when they called off their engagement [5] in 2013, they seem more in love than ever after getting back together [6].
