Miley Cyrus is a Guitar Girl

Miley Cyrus lunches at The Cheesecake Factory and shops around the Guitar Center in Los Angeles on Saturday.

The 15-year-old Hannah Montana star also picked up a few shopping bags full of goodies from the Tuso boutique inside the Sherman Oaks Galleria.

All day, Miley was accompanied by little sister Noah, 8, and her momager, Tish.

On her way out Tuso, Miley took a moment to sign an autograph for a fan!
