Rapper 50 Cent's energy drink has given a real boost to his bank balance, for drinks giant Coca-Cola has bought the firm behind it for a whopping 400 million dollars.

Coca-Cola closed the deal on Glaceau, the firm which produces the Vitamin Water range called Formula 50 on Friday, May 25 for4.1 billion dollars.

And since 50 Cent owns 10 percent of Glaceau, the buy means that he's just profited by 400 million pounds, states AllHipHop.com, reports Contactmusic.

In the meantime, the rapper is getting set to show off his classical skills in a new TV advertisement for the energy drink, when he conducts a symphony orchestra through a rendition of his breakthrough hit, In Da Club.

And, this is not the only sale that is sure to rake in the money for the rapper, for he's also put his 52 room Connecticut estate up for sale.

Boxer Mike Tyson once owned the mega-mansion that as part of divorce settlement was given to the boxer's wife, from whom 50 Cent bought it for 4.1 million dollar in 2003.

The 20-year-old luxury mansion has about 18 bedrooms, 37 bathrooms, a gym, dueling billiard rooms, racquetball courts and a disco.

50 Cent spent 6 million dollars in renovating the house, including adding a helicopter pad, an infinity pool and spa with a grotto and a movie theatre.
