The "My Heart Will Go On" singer is teaming up with bosses at licensing firm Epic Rights to create the line of home goods, active wear, beauty products, eyewear, travel products, and more.
The brand is yet to be named, but it will encompass the 48-year-old singer's passions for "family, music, entertainment and style", according to Billboard.
"In today's world, you need a coordinating and consistent branded approach to everything," CEO of Epic Rights, Dell Furano, said.
"On a global level, (artists) need to combine all areas - their music, performances, touring, website, social media - and launching a lifestyle brand was just a natural extension for Celine at this point in her career, particularly because it's all from her point of view."
