Ariana Grande: 'Seventeen' Magazine Signing!

Ariana Grande poses for photographs as she attends her Seventeen magazine fan signing on Monday (July 8) at Barnes & Noble at The Americana at Brand in Los Angeles.

“Wish I could have met everybody who waited but security said it was beginning to be a safety hazard & I was told to keep moving I apologize,” the 19-year-old entertainer wrote on her Twitter account.

“But on the other hand, I’m glad I got the opportunity to meet so many of you today. Ur all so nice. Hope you left smiling. Thank you again.”
