Joker: Folie à Deux star Lady Gaga has appeared in her second campaign for Pfizer, promoting the pharmaceutical brand's Nurtec migraine treatment.

The American actress and singer commented 'I really wish I had found Nurtec ODT sooner. If you’re suffering with migraines, I know we might have lots of different careers and backgrounds, but we share this thing in common. It feels good to tell you that it could be helpful to you'.
