Selena is currently on her South American We Own the Night Tour, and decided to switch up her set with the upbeat cover on Tuesday. The audience couldn't have been more excited -- everyone was singing the words at the top of their lungs.
The 19-year-old picked the perfect tune. 'Mr Saxobeat' spent eight consecutive weeks at No. 1 in Romania, Alexandra's home country, then took Europe, Canada, Australia and beyond, so it's known all over the globe.
"Regardless it's a blue eye shadow kinda day.." the singer also tweeted Tuesday along with an Instagram photo of her rocking blue lids, although we can't tell from the video if that is the eye makeup she was wearing on stage.
