The Come and Get It hitmaker's Strong Is Beautiful campaign will debut in August (15).

She says, "I've always loved using Pantene, so it's a dream come true to be the brand's newest ambassador. Not only because Pantene stands for strong, healthy hair but also because it encourages women to be their best selves.

"My style is constantly evolving and I love to take risks, so I'm always changing my hairstyle. I rely on Pantene to keep my hair strong and healthy so I can take on each day with confidence."

Gomez follows in the footsteps of Gisele Bundchen, Eva Mendes, Queen Latifah and Zooey Deschanel as a spokesmodel for the beauty brand.
