As she demonstrates with every twitch of her tweeting finger, Cher is a bona fide living legend.
With a scene-stealing apperance in Mamma Mia! Here We Go Again and her newly-released album of ABBA cover, Dancing Queen, looking set to be her biggest album in years, 2018 is truly the year of the Cher-aissance.
Of course, the Grammy, Emmy Award and Oscar-winning star has six decades of her experience when it comes to creating iconic pop culture events - but the younger among us might be lacking a proper Cher education.
So as the immortal diva celerbates her 73rd birthday today (20 May), we thought we'd create the ultimate beginner's guide to Cher's most iconic moments. Let class commence...
1) Appearing on Top of the Pops in black and white.
2) Looking smokin' hot in this performance of Gypsies, Tramps and Thieves.
3) The album cover for 1978's Take Me Home.
4) Attempting to go unnoticed in a Jackson 5 medley back in the day.
5) Correctly predicting exactly what her 'older' self would look like in this sketch with Bette Midler and Elton John (no really, it's uncanny).
6) This emo performance of Dark Lady (eat your heart out, Lana!)

18) This incredible video from impersonator Charlie Hides (which she loves).
19) This newspaper wig from the Woman's World video.
