Bell's palsy

Musician and TV presenter Tulisa Contostavlos also has recurring instances of Bell's Palsy, which developed after she suffered nerve damage in a horse riding accident.

The star did not disclose the cause of his condition, but fans speculated it could be Bell's Palsy, a nerve condition that causes paralysis to part of the face, or Ramsay Hunt Syndrome, in which a shingles outbreak affects the facial nerve near the ear, and cause hearing issues such as tinnitus.

She's also spoken about being diagnosed with Bell's Palsy - a type of paralysis that temporarily affects the ability to control the facial muscles - and having surgery and fillers when the condition made her face "drop".

Though the two women look different, they have both suffered from Bell’s palsy, a condition affecting about 100,000 people in the UK.

Amy quickly recognised how Bell’s palsy had affected Tulisa's face, saying "there's volume that lacks in her face, which is very similar to mine".
