Wanna see a WWE superstar steal the spotlight from Shania Twain ... at a Shania Twain concert!?!?!
Well, that's exactly what happened on Tuesday night in Canada when Twain pulled Kevin Owens out of the stands and brought him on stage.
Owens is a huge Twain fan -- "When" is his favorite song -- and he brought a sign to the show hoping to get Shania's attention.
The plan worked -- he got on stage ... and when Shania asked if he was "pro wrestler, Kevin Owens" ... he grabbed the mic and took over.
