Taylor Swift's 1989 Tour in Tokyo didn't have front acts, instead she filmed her BFFs and the video was played between sets.

Calvin Harris' girlfriend then explained why she decided to start his 1989 Tour in Tokyo, instead of the US which was the usual way she begins her tours.

"This year changed my life and I wanted to come here to say thank you," she said, and one of the reasons perhaps is Calvin Harris, whom she's getting serious with based on multiple reports.

Taylor Swift also acknowledged that most of those in audience are not native speakers of English.

"I'm looking out at an ocean of people that have been singing along all night and that's so beautiful that you would do that even if you don't speak English! It makes me feel so wistful and romantic that you would do that."

Calvin Harris' girlfriend enlisted her BFFs to make her tour a success.

"Everybody knows the 25-year-old beauty has a long list of famous friendships," said E! News.

"Luckily, many will be a part of every show in a pre-taped video airing during the show. Concertgoers spotted Selena Gomez, Karlie Kloss, Cara Delevingne and high school bestie Abigail Anderson on the big screen."

It seemed boyfriend Calvin Harris wasn't in attendance for Taylor Swift's concert in Tokyo, and he certainly wasn't included in the clip.

Calvin Harris and girlfriend Taylor Swift reportedly hit it off during the Brit Awards, and the relationship has the blessings of her BFFs.
