Before her gig in Australia, Clarkson hinted at her song choice on Twitter, posting "I am really excited about the fan request song tonight. Such a beautiful song. Hopefully I do Adele some justice :)"

We think Adele would be proud of Kelly's "Someone Like You" performance, even if the original singer's voice is impossible to match.
Celine Dion also honored the singer with a cover of "Rolling in the Deep" back in June.
