A photo of Lorde holding Taylor Swift's foot has gone viral - and raised plenty of questions.
The photo was posted overnight on Swift's Instagram account and shows Swift and Lorde posing with girl group Haim, rising star Serayah and actress Halston Sage on a two-seater bike.
Because of Lorde's foot-holding, it's quickly gone viral.

Swift captioned the photo "Real Love" but didn't supply an explanation for the foot-holding, leading some to start speculating.
Others took to Twitter in an attempt to explain the pose.
Perhaps there's a simpler explanation after all that: Swift is perched precariously on the bike and her feet can't quite reach the ground. Lorde may simply be helping her balance so she doesn't fall over in front of her friends.
Anyone thought of that?
