Miley Cyrus is Mo's Marvelous

Miley Cyrus keeps it cool in a cute cowboy hat as she grabs lunch with mom Tish at Mo’s restaurant on Saturday afternoon (August 8( in Toluca Lake, Calif.

After lunch, the 16-year-old starlet made a quick stop at Starbucks for a meeting. Miley also snapped a picture with an older fan outside the coffee bar.

Miley will be performing her new single, “Party In The USA” tomorrow at the 2009 Teen Choice Awards.
