Taylor Swift and Calvin Harris’ relationship has moved to the “I love you” stage — if one is to assume that Swift was mouthing those words at the 31-year-old DJ, whose real name is Adam Richard Wiles, during the finale of her fourth of five consecutive shows at the Staples Center in Los Angeles on Tuesday night.

In the video, we see the 25-year-old singer waving to the crowd and even curtseying after ending her show with her hit “Shake It Off.” The pop star then mouths the words “I love you,” and while they could be meant for anyone of Swift’s celebrity friends or even a special fan, Harris was spotted at the end of the runway, so it’s not the craziest thing in the world to assume the two have taken their romance to the next level. And there’s the whole fact that Swift “liked” the video posted on Tumblr, which seems to confirm who her “I love you” was for.

Aww, cute.
