One of the best parts of summer is all the fun concerts and festivals that blow through town. But we're not the only ones who get excited to see our favorite bands: celebs do too! Here's a guide to celeb-spotting at this summer's hottest tours. Who knows? You might just find Blake Lively or Jennifer Aniston standing next to you in the audience, waving a lighter and singing along to their favorite tunes.
Taylor Swift's Speak Now Tour
While some of Taylor's friends will be on their own summer tours, she still has loads more besties to count on for support. Emma Stone and Kellie Pickler, who Tay-Tay includes in her inner circle, will surely be singing along to "Story of Us" at her shows. And at the end of the summer, you might spot Katherine Heigl in the front row -- her hubby, Josh Kelley, is Taylor's opening act in Alberta and California.
