Taylor Swift and Calvin Harris are living together.
Since the 26-year-old singer finished her '1989' world tour late last year, she has moved into 31-year-old Calvin's Beverly Hills home.
A source told E! News: "Now that her tour is over, they are living together at his house in Beverly Hills while she is having some work done on her new home.
"They are definitely talking about their future together and the possibility of one day getting engaged. Making it work, despite their huge demanding schedules, and her tour, has proved to both of them that this is something that is serious and that could last. It's really cemented their commitment to one another."
Calvin and Taylor spent Christmas with her family in Colorado and were inseparable over the holidays.
The insider added: "They were in Colorado for Christmas together with Taylor's family. It was all about being in the snow, snow ball fights, lounging by the fire and relaxing. After Christmas they came back to LA together and rang in the New Year."
While Taylor is loved up with Calvin, it was recently claimed that she is annoyed that her friend Kendall Jenner has reconciled with her ex Harry Styles.
A source explained: "Taylor heard from a mutual friend that Harry and Kendall are back together and she is completely shocked. She can't believe that Kendall would actually date Harry, especially after their last conversation when she said she would never, ever get involved with him again.
"Taylor and Kendall actually bonded over dissing Harry and comparing notes on him."
