The 26-year-old eccentric singer will release her own "healthy drinking water brand" that will be supported by a multi million-dollar global advertising campaign, the New York Daily News reported.
"Gaga has been at the centre of a lot of attention over her weight increase. Losing her weight in such a short time and launching a healthy water drink may be part of a plan," a source said.
It is rumoured that Haus of Gaga, the star's creative team, are currently putting finishing touches to the drinks bottle. The 'Bad Romance' singer is said to want the design to be kept top-secret until the launch.
"We know that the water drink is due out in the near future. No-one has seen prototypes of the bottle. Gaga water is something that has been in the pipeline for a few months, and now things are really gearing up to an announcement and high-profile launch," the source added.
Gaga recently launched her first perfume 'Fame' with a high-profile party at the Guggenheim Museum in New York. It was reported that the perfume may have sold 6 million bottles in its first week.
