This actress, singer, and Grammy winner announced she might be extending her Sin City residency and to celebrate, she rang in the New Year like a queen. Lady Gaga's Vegas performance included pouring champagne on her co-star and smashing a wine glass on the ground. We're convinced it was her best concert yet.\nOn NYE the pop-star made two appearances throughout the night: one at Park Theatre for "Jazz + Piano" and the other at Brian Newman's "After Dark" show.\nDuring the "After Dark" bash, Gaga did something unexpected.\nIn the video, the singer can be seen holding a very full glass of what appears to be champagne before taking a huge gulp. After, she tosses the remaining booze at her longtime friend Brian Newman.\nThe jazz musician looked surprised by this, but quickly smiled and laughed it off.\nGaga, completely in the moment, continued her song and began circling the empty glass around her head before tossing it to the ground.\nBoth pals laughed and hugged it out on stage, afterward. If that's not an epic way to start the new decade, then we don't know what is.\nThis video of Lady Gaga actually smashing a wine glass on stage is rigging in the new year of 2020 pic.twitter.com/6w5ZrSrzmz— Jake ツ (@IStandWithGaga) January 1, 2020\nOne user commented on the post and said, "Looks like fun times!!!!😋" while another person wrote, "The look she gives him afterwords of sheer self enjoyment."\nLady Gaga at Brian Newman’s After Dark Show last night in Vegas. pic.twitter.com/8Dho8khedE— GAGAIMAGES (@gagaimages) January 1, 2020\nHer outfit was giving us major 1920s vibes.
