Taylor Swift backstage at SNL

Taylor Swift takes a break backstage during rehearsals for Saturday Night Live and talks to MTV about her album Fearless.

The 19-year-old “Love Story” singer shared, “I cannot believe [the album sales]. I get a phone call every single week. I honestly can’t believe that. The fans have been so good to me. The fact that people actually like it, I can’t believe it.”

This Saturday, Taylor will take the musical guest spotlight on the late night comedy show with host How I Met Your Mother’s Neil Patrick Harris.

Neil joked about Taylor’s height, saying, “Taylor Swift is lovely and — contrary to popular belief — is pretty tall. She’s, like, 5′7 or 5′8” and then wears heels and is 7′2″. Next to her I look like Ryan Seacrest.” Ouch, Ryan!
