The clip saw the duo show off the sights of their recent travels, including the Eiffel Tower, the Cologne Cathedral, and, of course, the GUTS World Tour stage.

Olivia and Madison lip-synced to various "Troy and Abed in the morning" moments from the sitcom Community as they showed off each locale.

The get him back! artist previously gave a glimpse of her time spent with Madison in a recent photo dump from various spots across Europe.

Olivia and the 22-year-old actor's friendship goes back several years, as the two got their start on the Disney Channel as the leading ladies of Bizaardvark alongside Jake Paul.
