On Friday, she treated fans with a glimpse as to how she achieved her glamorous transformation with a post on TikTok. The clip started with the 50-year-old showcasing her natural beauty, before flicking her hair and effortlessly transforming into the super elegant look that she showed off earlier in the week. After donning her new look, and to the tune of ABBA's Gimme! Gimme! Gimme! (A Man After Midnight), she performed a little shimmy as the video ended.

A third stunned follower wrote: "Hold up, wait a minute, there is no way this gorgeous specimen is 10 years older than me, 10 years younger I may believe, there is some witchcraft going on here."
