*50 Cent earned $8.7 million in real money on Monday – all thanks to some tweets, the New York Post reported.

The rap star helped pop the shares of the penny stock of H&H Imports, in which he has a stake, by talking it up on Twitter over the weekend.

“You can double your money right now. Just get what you can afford,” he tweeted.

H&H owns a marketing firm called TV Goods that was founded by Kevin Harrington of ABC reality show “Shark Tank” fame. 50 later added: “Check out TVGoods.com official site of Kevin Harrington.”

H&H stock gained 29 cents to 39 cents on Monday. That helped boost the value of the singer’s stake by $8.7 million, according to Post reports.

50 Cent, aka Curtis Jackson, reportedly received 30 million shares of H&H in a private placement last October. In March, the firm’s auditor raised questions about its ability “to continue as a going concern.”
