Phoenix is already an avid dancer, with his proud mom showing off his dance moves whenever she gets a chance. In January, Hilton shared an edited version of an earlier TikTok, where Phoenix danced to WHAM's "Last Christmas." This time, it was edited so Phoenix appeared to be dancing to his mom's single with Steve Aoki, "Lighter," as the background color flashed and changed. "#Sliving runs in the family🥳 #MiniSliver 👶🏼," she captioned the video, also joking, "When you realize that clubitis is hereditary and your mom is Paris Hilton." That same day, the DJ mom shared another video which showed Phoenix dancing on Reum's lap during a plane ride. As she cooed, "Dancing!" Phoenix began to wiggle, smiling wide. "Go Phoenix!" she cheered as he laughed and continued to move. "Baby P Sliving on the plane✨👶🏼✈️✨," she captioned the video.
