For her upcoming music video for "Bad Blood," Taylor Swift almost add all of her friends to star on it. The video started filming in Los Angeles last Sunday morning, even though it was just a few days ago when Swift shocked her fans with regard to the news that her mom has cancer and is currently trying to battle it out.

Taylor Swift reportedly included Cara Delevingne, Zendaya and Hayley Williams for her “Bad Blood” music video. E Online reports that the three friends of Swift were all spotted with dramatic eye makeup and sideswept hair. For her part, Taylor was seen bundled in a white robe, hiding her costume for the video. It is no secret that the three are really close to the “Red” singer, along with all the other girlfriends of Taylor such as Lena Dunham and Selena Gomez.

While there is no confirmation for Taylor’s camp that the three will be working with her, this would not come off as a surprise because Taylor had asked her friends to join her in some of her past videos already. For instance, on her “22” music video, Jessica Szohr of "Gossip Girl" was tapped to work with her.

Going back to work so soon, after she announced her mom has cancer just shows how professional and brave Taylor can be. Just three days before this shoot, the “Style” singer took to her Tumblr to post about her mom’s cancer and advise people to start caring for their parents and ask them to go for their checkups. "[My mom] wanted you to know because your parents may be too busy juggling everything they’ve got going on to go to the doctor, and maybe you reminding them to go get checked for cancer could possibly lead to an early diagnosis and an easier battle… Or peace of mind in knowing that they’re healthy and there’s nothing to worry about," Swift wrote. "She wanted you to know why she may not be at as many shows this tour. She’s got an important battle to fight."

"Bad Blood" will be the fourth video released from Taylor’s “1989” album. The first three were "Shake It Off," "Blank Space" and "Style,” all of which made waves among her fans, cementing her career as a true blue pop star, instead of a country star singing some pop songs.
