What are friends for? If you’re Selena Gomez and Taylor Swift, it’s to help promote your BFF’s song by making a video to go with it. That’s what Selena did, by filming a dance video to Taylor‘s latest song, ‘I Knew You Were Trouble.’
The Spring Breaker‘s star and a few friends came up with a dance routine to Taylor‘s hit, filmed it and then tweeted, “SO Cheesy, I know but I’m glad I’ve got my girls….. and Gweny… 
@tayorswift13 we love you!!!”
Taylor seemed to love her friend’s video, tweeting back,”@selenagomez I love you so.”
Not that Taylor’s song needs it, but Selena – along with Justin Bieber and Ashley Tisdale – helped Carly Rae Jepson‘s ‘Call Me Maybe’ go viral earlier this year with their adorable homemade video.
Check out Selena and friends in their homage to Taylor:
