Taylor Swift and boyfriend Calvin Harris recently celebrated her BFF's birthday — Victoria's Secret Angel Karlie Kloss turned another year older on Monday. The "Blank Space" singer posted a snap on Instagram of the birthday girl, 23, cooking at the kitchen with DJ beau Calvin Harris hanging out in the island counter, as per Daily Mail.

Taylor Swift, 25, captioned the post: "Some of my best memories have been with this girl, laughing in the kitchen. Happy Birthday to the ray of light that is @karliekloss."

Taylor Swift and Calvin Harris, 31, had been dating since the start of this year after being introduced by Ellie Goulding, who is their mutual friend.

The Scottish DJ said in a Kiss FM interview, "It's going absolutely fantastic."

"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..." he added.

Harris also revealed that despite having his budding romance exposed to the public eye, he and Taylor try to exhaust their efforts to ignore the attention that they get every day.

Contactmusic.com reported that Taylor Swift and beau Calvin Harris were looking for a house in Los Angeles to serve as their love-nest.

The source stated: ''They're ready to take that next step. They're looking forward to a new place they can move into together and decorate together.''

Harris has been supposedly staying at the singer's extravagant penthouse in the city of New York, where he has been taking care of her pet cats while she was in North America for her 1989 World Tour.

Venture Capital Post also reported that Taylor Swift's boyfriend was shopping for a 10-carat ring valued at $500,000. It was also disclosed that before Calvin Harris gets the hand of the Grammy award-winning singer/songwriter, he has to go through her parents first, most especially, her dad.

Meanwhile, Calvin Harris downplayed the rumors that he and the "Bad Blood" hitmaker were moving in on one house together and also tying the knot.

He said, "It does get more and more ridiculous, from me apparently being allergic to cats or Taylor and I are moving in together or we're getting married next week. It's a lot but you've just got to take it how it is which is that it's a news story that people read but it's just not real life."

Well, time will tell if Taylor Swift and Calvin Harris would indeed level up their relationship. For now, their fans will have to wait for further updates.
