Taylor Swift shot a new music video in Malibu yesterday. She ran on the beach with a group of young women, took part in a human pyramid, and later rode around in a shopping cart in a parking lot. Taylor didn't say which song she was making the video for, but she did reveal that the cast she filmed with was made up of her friends. She tweeted earlier today, "Leaving LA now after the best day with my friends. Almost forgot it was a video shoot. Can't wait for you guys to see it." While Taylor was excited to talk about her new video, she kept mum on the stir she caused earlier this week when she allegedly called out ex-boyfriend Harry Styles during her Grammys performance.
