And here I was thinking she was an N*Sync kinda gal…haha.

The pop princess stopped by to say hello to the Backstreet Boys before their show at the Pechanga casino in California Friday. Afterward, she joined the crowd to cheer the boy band on.

To be honest, I didn’t even know they were on tour! The guys also took the stage at New York City’s Radio City Music Hall last weekend with New Kids on the Block. Now there’s a show the teen in me would’ve enjoyed :)
