Lady Gaga will launch a diet drink "in the near future".
The singer's weight has come under scrutiny recently after photos emerged showing her looking larger than usual.
It has now been claimed that the pop star's weight gain is part of a multi-million dollar global advertising campaign to tie in with the launch of her water brand.
"We know that the water drink is due out in the near future. No one has seen prototypes of the bottle," an insider revealed to the New York Daily News.
"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 Bad Romance star will allegedly lose weight before the drink's launch.
Sources claim this is part of the 26-year-old's plan to market the product.
Her Haus of Gaga creative team are reportedly putting the finishing touches to the new product.
"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," the spy continued. "Everyone at Gaga HQ is keeping very tight-lipped. There are plans being prepared for marketing strategies."
