Katy Perry was all about the sock bun at the 56th Grammy Awards in Los Angeles on January 26. Her hair was pulled back in a twisted 'do on top of her head, but just a day later, the pop star completely changed up her look. How she had time to hit up the hair salon between Grammy parties and red carpets, we do not know!

The PRISM singer stepped out for the The Night That Changed America: A GRAMMY Salute To The Beatles event in Los Angeles on January 27, showing off short choppy bangs. Katy paired the new hairstyle with a loose-fitting, floral Dolce & Gabbana dress. Looking good, KP! As for her getup the night before? Katy also went for a designer look at the Grammys, wearing a Valentino gown with music notes on it.

During the Beatles event, Katy took to the stage to perform The Beatles' "Yesterday," and her boyfriend, John Mayer, sang "Don't Let Me Down” with Keith Urban.

We think Katy looks, ahem, bangin' no matter what hairdo she has, but what are your thoughts? Sound off in the comments!
