Fans were treated to a duet by Keith Urban and Carrie Underwood during Urban's concert Saturday night in New Zealand.
Urban usually performs "The Fighter" to a video of Underwood singing her parts but, this time, the country stars performed the song together.
Underwood is the opening act on the New Zealand and Australia leg of Urban's ripCORD World Tour.
So, it's possible she will join Urban on stage at all eight of his upcoming shows across Australia.
We are completely jealous.
