Kim Kardashian and Scott Disick are being sued for US$40 million ($67m) for promoting a lottery on their Instagram pages that has been accused of being a scam.
Entrants were allegedly lured with the promise of prizes such as first-class tickets to Los Angeles, a three-night stay in Beverly Hills and even US$100,000 ($167,000).
Claims that the games are a scam are disputed, with sources close to Curated Businesses, the Australian company that organises the lotteries, telling TMZ they have proof that there have been legitimate winners.
Plaintiffs allege that their entries in the contests led to them being bombarded by advertisements that were targeted at them after their personal information was sold, claiming that they were "invaded by hundreds of advertisers, some of which are soliciting the plaintiffs with potentially offensive and unwanted content".
"Just a short 20 years ago, Oprah was giving away cars and cash," the plaintiffs write in the suit.
