Kylie Jenner won Halloween this year when she dressed up as Christina Aguilera from her iconic “Dirrty” music video. Jenner donned red and black chaps and a platinum blonde wig with dark streaks to complete the look. Aguilera appreciated the nod and even gave Jenner a shoutout on Instagram. But the singer was apparently so impressed that she wanted to see the get up in person. At Aguilera’s request, the 19-year-old lip queen was in attendance for an early celebration of the singer’s 36th birthday on Saturday. She once again dressed as the pop icon, this time in yellow. The duo snapped several pictures together and even shared a racy kiss. Why relive your younger days when you can just have a Jenner do it for you?
