James Hetfield infamously got hit by stage pyrotechnics in Montreal when Metallica was touring with G 'n R in the 90’s.

Margaret Hamilton.

I’m pretty sure she got reconstituted into a pitcher of pure witch juice with the addition of water…

Jack Cassidy burned all up, though.

Paul Walker.

This needs to be a Wikipedia category.

Do you count race car drivers as celebrities? I’m sure many of them have caught fire.

Zelda Fitzgerald died in a fire.

Like Niki Lauda. One of the few to actually survive a fire in the 70’s.

Uriah Heep’s lead guitarist(?) or bassist(?) (there’s conflicting accounts) got electrocuted onstage in '74.

The odd Spinal Tap drummer might’ve caught a spark or two.

And then there’s that nutty Arthur Brown guy.
From wiki:

Brown quickly earned a reputation for outlandish performances, which included the use of a burning metal helmet, that led to occasional mishaps, such as during an early appearance at the Windsor Festival in 1967, where he wore a colander on his head soaked in methanol. The fuel poured over his head by accident and caught fire; a bystander doused the flames by pouring beer on Brown’s head, preventing any serious injury.[8] The flaming head then became an Arthur Brown signature.

Vivian Stanshall of the Bonzo Dog Band.

She wasn’t burnt by flames but Cassandra Peterson (aka Elvira) was badly burned in a kitchen accident when she was a toddler. She still has scars that she conceals with make-up.

Jack Palance. Maybe.

With the outbreak of World War II, Palance’s athletic career ended, and his military career began as a member of the United States Army Air Forces. Palance’s face, which took many beatings in the boxing ring, was said to have become disfigured while bailing out of a burning B-24 Liberator bomber during a training flight over Southern Arizona (where Palance was a student pilot). His distinctive cheekbones and deep set eyes were said to have been the result of reconstructive surgery.
The story behind Palance’s face was repeated numerous times (including in respected film reference works), but upon his death, several obituaries of Palance quoted him as saying that the entire story had been contrived: “Studio press agents make up anything they want to, and reporters go along with it. One flack created the legend that I had been blown up in an air crash during the war, and my face had to be put back together by way of plastic surgery. If it is a ‘bionic face’, why didn’t they do a better job of it?”

A blacksmith in our local SCA barony is known for setting himself on fire from time to time, but you’ve probably never heard of him.

Anthea Turner, certainly, though I believe she didn’t suffer any severe harm.
