A breakdown of everything you need to know for Beyoncé's Cowboy Carter Tour, including merch prices, what to bring, and how to get last-minute tickets.

Beyoncé kicked off her Cowboy Carter Tour on Monday, April 28, at SoFi Stadium in Los Angeles by including a rare video of her 7-year-old son, Sir, in her performance.
