Priscilla Presley, 72, leaves viewers stunned by her appearance during recent TV interview

We should all look so young at 72!

Priscilla Presley left viewers -- and Twitter -- totally stunned during a recent TV appearance in the United Kingdom, looking a fraction of her age as she sat down for an interview on "Lorraine."

Responses were mixed, as some praised her for her youthful-looking face and others questioned her methods used to achieve it.

For comparison, keep in mind that Elvis Presley's former wife has always been a beauty. Here they are fifty years ago, when they tied the knot:

Five decades later, she truly is still a beauty, regardless of what steps she may have taken to preserve her looks! Rocking deep burgundy hair and a red lip, she visited "Lorraine" to promote "Christmas with Elvis and The Royal Philharmonic Orchestra."

About a decade ago, Presley's rep acknowledged that she was "one of the many documented victims" of fraudulent cosmetic doctor Dr. Daniel Serrano.

"Serrano was a good-looking doc from Argentina who hooked into Hollywood's social A-list and started giving them what he claimed were miracle injections that worked better than Botox," TMZ wrote at the time. "In fact, Serrano was injecting industrial, low-grade silicone similar to what's used to lubricate auto parts in Argentina into the faces of these women."

Serrano was imprisoned following an investigation.
