Here's the title track off Taylor Swift's new album Lover and we're ... loving it!

Swift told fans during an online chat yesterday that the music video's concept was inspired by lyrics from "You Are in Love" off her 1989 album: "And so it goes / You two are dancing in a snow globe ’round and ’round." And while she doesn't refer to beau Joe Alwyn by name, the words were clearly inspired by their relationship: "I’ve loved you three summers now, honey / But I want them all."

And while we kinda wish Alwyn starred as her love interest in "Lover," TSwiz explained the casting during her YouTube Live session, on Thursday: "The leading man in this video [Swift's backup dancer Christian Owens] is someone I have performed on stage with for years. [He was the] leading man in the ‘King of My Heart’ performance every night on the reputation tour. Every night I could see how expressive he is and just how heroic and what an amazing actor he is as well.” Good choice!
