A number of major health groups have come together in protest of Katy Perry's recent partnership with Pepsi.
According to "USA Today," the groups will be taking out a full-page ad in Tuesday's issue of "Variety" to call on the pop star to stop marketing the sugary drink to young people.
Beyonce received similar backlash for her multi-million dollar endorsement deal with Pepsi earlier this year.
Katy, however, has not signed on for a long-term contract with the company.
Pepsi has sponsored parts of the promotion for her upcoming "Prism" album, including the singer's performance at the MTV VMAs in August.
The protesting health groups released an open letter, saying they are "focusing on Katy because she's so popular with young people."
