Cher - Then
Cher's 1991 book, "Forever Fit: The Lifetime Plan for Health, Fitness, and Beauty" promised a one-stop-shop for a life's worth of health tips. Cher was one of the most reputable beauty gurus in the game, and how well she's aged since the 80s is a testament to her foolproof routine.
Cher - Now
When Cher performed at the 2017 Billboard Music Awards, it was is if she'd been transported back to the 80s when her career was at its peak. The 71-year-old superstar clearly still has it - she can do a five-minute plank! She credits her active lifestyle to her physique and overall wellbeing.
