She stopped to snap some pics with a crowd of waiting fans.
The 26-year-old singer's London appearance comes just weeks after her Malibu home, which she shares with Australian boyfriend Liam Hemsworth, was completely destroyed by the California wildfires.
The appearance also comes days after her storage unit got broken into.
Law enforcement sources told TMZ that someone got into Miley's storage unit in the San Fernando Valley and made off with some valuable guitars.
The total value of the missing items is more than $10,000.
It's unclear how the thieves got into the unit, but the heist nearly went unnoticed, TMZ reports.
