Starting her weekend with a trip to the studio, Miley Cyrus worked on her music in Glendale on Friday (March 1).

The "Hannah Montana" star was dressed in all black with a midriff-baring short-sleeved top, black pants, and flats while carrying her leather jacket.

Though cheating rumors have been swirling since the 20-year-old singer/actress's fiancée, Liam Hemsworth, left the Chateau Marmont with January Jones after the Grey Goose Pre-Oscar Party. Miley, meanwhile, was with her mother at Elton John's annual bash.

However, it appears that the two are still going strong as the photos on Friday show the future Mrs. Hemsworth still sporting her glittering engagement ring.
