While some social media users simply asked what happened to her, others were harsher.

“Her face looks like a mask!!! What happened to her?” one person wrote. Another wrote, “Leave the plastic surgery alone Priscilla Presley.”

Presley, 71, was talking about her late ex-husband on British TV at the time.

The grandmother of two has spoken in the past about having botched plastic surgery. She has said low-grade silicone — similar to what mechanics use to grease car parts — was once injected into her face.
