There is no denying that Taylor Swift is madly in love with her current beau. A picture circulating on Tumblr shows Tay-tay wearing Calvin Harris' go-to gray t-shirt. The photo was taken Aug. 19 at a Loft '89 meet-and-greet with fans.

Obviously Swift was wearing the exact same grey t-shirt that Calvin has been seen wearing on several occasions. Aside from being cute, Swift wearing Harris shirt actually tells a lot about their relationship.

The exact meaning of this can be traced to Tay-tay's 1989 album You Are in Love, describing how two people who are madly in love with each other and all the little things they do to prove it. The 25-year-old country-turned-pop crooner penned the song after being inspired by her 28-year-old friend Lena Dunham and her long-time 31-year-old boyfriend Jack Antonoff.

The emotional track speaks of wearing your boyfriend's shirt as a clear sign of falling head over heels.

Taylor references with the lyrics that reads in part: "Morning, his place / Burnt toast, Sunday / You keep his shirt / He keeps his word / And for once you let go of your fears and your ghosts / One step, not much / But it said enough / You kissed on sidewalks / You fight and you talk / One night, he wakes / Strange look on his face / Pauses, then says / 'You're my best friend' / And you knew what it was / He is in love."

It seems Swift is keeping Harris' shirt.

And in another sign that the singer is really taking her relationship with Harris to the next level, Taylor mouthed the words "I Love You" to her Scottish DJ boyfriend Calvin at the end of her song Shake It Off. Taylor said those words to as she took her final vow Monday night as part of her 1989 tour. Harris was with the crowd to watch another one of her awesome performance, reported the Daily Mail.

At the end of the song, Taylor went back to the end of the runway and looked straight into the eyes of her boyfriend and sweetly said, 'I love you!' to the delight of the fans.
