The arrived in Australia last week but it seems life on the road has led to some confusion for the Guns N' Roses.
While performing in Melbourne at the MCG on Tuesday night, an announcer for the legendary rock band said "Hello Sydney!" - introducing the group on stage as Sydney instead of the Victorian capital!
Not happy about being confused with their northern neighbours, Gunners fans started booing as the band started playing their opening song.
While the slip-up wasn't addressed on stage, the band took to Twitter after the show to apologise for the mix-up made by their long-time sound tech.

"Melbourne! Accidentally after 30 years McBob made an error, we're truly sorry. Thank you for coming out tonight!" They tweeted.
The band had kept the 70,000 strong crowd waiting an hour before hitting the stage at 9pm.
Many fans took to social media to share the amusing opening blunder with one user tweeting, "Hahahah most hilarious start to a show in #Melbourne ever.... "Hello #sydney!!!"..... Crowd responds yayyyyyyy.. wait... What? #GunsNRoses."
