Watch Taylor Swift Sing 'This Kiss' Into a Gatorade Bottle

Taylor Swift wears a cute crown on her head while spending a night on the town on Saturday evening (March 14) in Los Angeles.

The 25-year-old singer, who sported a bandage on her leg due to a cat scratch, was joined by her younger brother Austin.

“Happy Birthday, Este!! Ever since you, Alana, and Danielle adopted me into your wolf pack, life has never been the same. @haimtheband,” Taylor captioned an Instagram video earlier in the day.
