It’s a Love Story, baby, just call me Adam? Things are heating up between Taylor Swift and her boyfriend of six months, Calvin Harris. In fact, it’s getting so serious that the “Blank Space” singer is not calling the Scotland-born DJ, 31, by his well-known stage name. 

“Taylor always calls Calvin by his birth name, Adam, and never Calvin in private,” a source close to the couple exclusively tells Us Weekly. "Taylor gets all dressed and glammed up whenever she is going to see him to look her best.”

Shall we call them “Taydam”? 

Swift, 25, whose exes include (but are not limited to) Harry Styles, Conor Kennedy, Jake Gyllenhaal, John Mayer, and Joe Jonas, seems to be rather smitten with her new love. 

"She's head over heels,” the source continues. “She hasn't been in love like this before!"

For his part, Harris seems equally invested in their romance. In addition to accompanying Swift to the Billboard Music Awards in May, he also defended her in a very public Twitter feud with former One Directioner Zayn Malik.

"It’s going absolutely fantastic," Harris told KISS FM UK in July. "It’s interesting, because obviously there’s different things written about it every day and even if we don't do anything publicly for a while, someone will make something up."

Prior to Swift, Harris dated Russian supermodel Anne V in 2013, British singer Rita Ora from 2013 to 2014, and model Aarika Wolf, whom he met on the set of a music video.
