But what's on her face and why?
Taylor Swift wished her friend British model Lily Donaldson a happy birthday on Friday (Jan. 27), sharing a selfie that'll have you asking some questions: Namely, what's on her face?
The black and white photo Swift posted to Instagram shows the now 30-year-old Donaldson covered in what looks like face paint. But without context, the reason behind the model's makeup is unclear.
"I love you," Swift wrote. "Happy Birthday!"
