1984 has zero celebrities - they don't and can't exist in that world.
The only figure with a face is big brother, and he didn't exist. I think Goldstein had no face?
If the proles (85% of the population) had celebrities, they would not be actual people : https://en.m.wikipedia.org/wiki/Prolefeed
"Below that come the dumb masses whom we habitually refer to as 'the proles', numbering perhaps 85 per cent of the population."
"What opinions the masses hold, or do not hold, is looked on as a matter of indifference. They can be granted intellectual liberty because they have no intellect."
"There was a whole chain of separate departments dealing with proletarian literature, music, drama, and entertainment generally. Here were produced rubbishy newspapers containing almost nothing except sport, crime and astrology, sensational five-cent novelettes, films oozing with sex, and sentimental songs which were composed entirely by mechanical means"
