Christina Aguilerais jumping right into TikTok and the holidays in retro fashion…

The 39-year-old half-Ecuadorian American singer, one of the newest members of TikTok, is literally a genie in a stocking.

“psssttt just joined #TikTok!” Aguilera wrote on her other social media accounts, Twitter and Instagram on Saturday, where she shared an amusing short clip of herself jumping into a giant Christmas stocking to the soundtrack of her classic hit “Genie in a Bottle.”
