LOS ANGELES (AP) - Will Smith and his 19-year-old son, Jaden, are announcing their latest collaboration, but it has nothing to do with music or movies.

The Smiths have founded an eco-friendly bottled-water company called Just, which is unveiling a new line of flavored waters next month.

The father-son team created the company in 2015, but the elder Smith says he wanted to wait until it gained momentum on its own merits before revealing the brand had celebrity backing.

Just was borne of Jaden Smith's love of the ocean. He saw plastic bottles and other trash in the water while he was a youngster out surfing, and as he got older and learned more about the environment, he wanted to do something about it. Just water's packaging is mostly made from renewable resources.
