Celebrities earn up to $50,000 a month promoting products on Twitter | News.com.au: "Ad mogul on how Twitter celebs sell out
They can earn 'up to $US5000 a tweet'
Advertisers pre-write celebrity messages
CELEBRITIES can earn up to $50,000 each month promoting products ranging from cars to clothes on microblogging service Twitter, according to a British entrepreneur.

Arnie Gullov-Singh's comments came as the carmaker Range Rover prepared to announce Monday that it recruited 40 people - including the British model Daisy Lowe - to drive one of the company's new cars and recount their experiences on Twitter.

Among those recruited by Mr Gullov-Singh - a Bristol University graduate who now lives in Los Angeles - to promote products on Twitter are the rappers 50 Cent and Snoop Dogg, as well as actress Kirstie Alley.

The practice raised concerns that fans who follow the stars on Twitter might not be aware that the promotional tweets were paid for.

Mr Gullov-Singh, 38, created a vast industry of corporately branded tweets in the past year.

As chief executive of Ad.Ly, he signed up 5000 celebrities to praise companies including Coca-Cola and Microsoft, with the stars earning up to $US50,000 ($51,020) a month."
