Maren Morris gave fans a thrill when she performed her hugely successful crossover hit "The Middle" live for the first time in the wee hours of Sunday morning in Las Vegas.
Morris hit the stage at the Omnia dance club around 2:30 in the morning and sang the chart-topping smash with Zedd for about 2,000 people.
Zedd brought Morris up to the stage by saying, "I've got a very special guest tonight. We made a song together, but we've never performed it together. So this is the very first time."
