A new, behind-the-scenes video shows the making of Taylor Swift's latest single, "Gorgeous," [1] and it's pretty fascinating to watch her songwriting process. Also intriguing? As Swift plays around with the lyrics, we get a glimpse into some of the phrases that didn't make the final cut — including a likely Calvin Harris reference [2]. The final "Gorgeous" lyrics [3] feature what's probably a nod to her DJ ex: "And I got a boyfriend, he's older than us / He's in the club doing I don't know what." In the new video, though, we see Swift trying a few different takes:

• "And I've got a boyfriend, he's older than us / I haven't seen him in a couple of months / I go through phases when it comes to love."
• "And I've got a boyfriend, he's older than us / I haven't seen him in a couple of months / My reputation precedes both of us."
