Christina Aguilera celebrated the end of 2019 during a sold out show at Planet Hollywood Resort & Casino''s Zappos Theater in Las Vegas. As midnight crept in, the 5-time Grammy winner was so busy meandering on stage, she actually MISSED the 2020 countdown and asked the audience to fake it with her!

The 'Drrty' singer sported several custom changes during her show, and at point while sporting a sexy white leotard from designer Gareth Pugh and costumer Karen Clarkson, Xtina suffered a major wardrobe malfunction which revealed her black nipple pasties, narrowly escaping a serious embarrassment!
