50 Cent, aka Curtis Jackson, reportedly lent his star power to a no-name penny stock company by tweeting about them over the weekend.
"You can double your money right now. Just get what you can afford," he tweeted.
On Monday, the company -- H&H Imports -- paid the celeb for his social networking. H&H is a money-losing venture based in Clearwater, Fla., the New York Post noted Tuesday.
"They are no joke get in now," Jackson told his 3.8 million followers. In exchange for selling out some ad space on his Twitter account, Jackson received 30 million shares of H&H and a series of warrants granting him the opportunity to cash in as the stock rises.
On Monday, H&H closed the trading day out at 39 cents, giving Jackson's 30 million-share stake an $8.7 million boost.
