Due to some of Cher's tweets over the last few weeks, a small number of Cher's 3.6-million Twitter followers have speculated that the 72-year old pop icon is working on an album of Abba covers.
The Academy Award-winner is about to begin a promo campaign for her upcoming appearance in next month's Mamma Mia: Here We Go Again, for which she recorded covers of Abba's Fernando and Super Trouper -- the former a solo performance whilst the latter is believed to be an ensemble effort featuring Cher.
