The glamorous ex-wife of Pakistan cricketer Imran Khan had instructed her followers on the microblogging site never to call her a socialite again, reports the Telegraph.
But fewer than 30 responded to her call to arms. And there was insurrection in the ranks.
"Keep calling her a socialite," posted one of the followers, Neil Hutchinson.
"Socialising seems to be all we see her do," another, who gave her name only as Jenny, remarked.
Kit Hume wondered why the daughter of the late tycoon Sir James Goldsmith could not see the irony in using a social-networking website to instigate such a campaign.
Jemima, who turns 37 this month, managed to find the time in her busy day to send 18 messages in a two-hour period alone on Twitter.
"'Socialite' is an insult to any self-respecting person and, besides, my friends all accuse me of being an anti-socialite," she wrote in one of them.
"Calling me a 'socialite' is such a lazy way for journalists to undermine me," Jemima had complained last month via the social-networking site.
