Miranda Lambert and Dierks Bentley are having a whole lot of fun on the Locked and Reloaded Tour -- which they referred to as an adult jungle gym -- even branching out with a cover of Gotye's 'Somebody That I Used to Know.' 

The two country stars do a terrific rendition of the multi-instrumentalist and singer/songwriter's phenomenal hit, which won Record of the Year at the 2013 Grammys and was No. 1 in 26 countries. The country stars are both dressed casually, with Bentley in jeans and a black baseball cap and Lambert donning a sparkly silver miniskirt paired with a black T-shirt.

The 'Mama's Broken Heart' hitmaker showcases her powerful vocals, which blend effortlessly alongside of Bentley's harmonies and guitar strumming, and it's just another reminder of how great these two country stars sound together, especially after a few months on the road together.
