Adele invite impersonator on stage at her concert in Washington

She told him: "You look amazing. I actually really like your dress!"

Kris later told Seattle's Q13 radio station about the surreal experience.

He said: "I wanted her to know that her music not only is amazing but it touches people in more ways than she probably even knows, and I didn't want to miss my opportunity to tell her that she really helped me to become the person I am today."

The 28-year-old singer previously revealed her love for impersonators and she even did a prank on her own sketch show on the BBC whereby she dressed up as her own impersonator and fooled 10 professional Adele lookalikes.

At the time, she said: "Nothing quite prepared me for walking towards, like 10 other girls dressed up as me, that was pretty overwhelming, but the whole thing was funny, but also really, really beautiful, and I cried a lot at the end once I revealed myself."

And Adele's latest on-stage antics come after she accidentally locked lips with a fan last week at Vancouver's Pepsi Live at Rogers Arena.

After the mother of one - who has three-year-old son Angelo with her partner Simon Konecki - performed with the concert-goer she leaned in to hug the unnamed man and give him a kiss on the cheek.

However, footage of the fan sees him swiftly turn his head and catch Adele's endearing gesture on the lips.

But the 'Send My Love (To Your New Lover)' hitmaker wasn't angered by the fan and turned to her live audience to show her bewilderment at the event and laugh it out.
