Taylor Swift's friends have given her DJ beau Calvin Harris the squad's seal of approval.

The singer's fearsome squad includes supermodels Gigi Hadid, Karlie Kloss, and Kendall Jenner plus singers Lorde and Selena Gomez. And she's made it very clear that her girls are important to her, even going so far as to include them in her stage shows while on tour.

However, Calvin, appears to have had no trouble charming them, and buddying up to singer's brother Austin, as the pair celebrated dating for a whole year recently.

"They're super happy together," a source told People magazine. "He gets along with her friends. They all like him and there's no drama."

This must come as welcome news to the Bad Blood singer, who built a strong circle of female friends who stuck by her during her single years.

Calvin, 32, and Taylor, 26, enjoyed a romantic beach holiday together earlier this month (Mar16) and both shared envy-inducing photos on their Instagram accounts. The couple's relationship appears to be going swimmingly, and a source even told Britain's Heat magazine it's going so well they’re considering an even bigger commitment.

“Taylor and Calvin had the perfect holiday. They didn’t argue once and it really cemented on how in love they are. It’s the most healthy and mature relationship Taylor has ever been in.

"They’ve regularly talked about marriage and have even discussed having children. Everyone thinks it’s only a matter of time before Calvin proposes.”
