Roar singer Katy Perry has teamed up with H&M to star in the brand's 2015 holiday campaign, debuting in November.

Perry commented 'H&M was one of the places where I first began cultivating my personal style. I have continued to love integrating H&M pieces into my wardrobe throughout the years. One of the reasons I love the holidays is being able to dress cosy and cute, which H&M executes so well for every budget'.
