Kate Hudson's athleisure fashion brand Fabletics is teaming up with the UN on a long-term 'girl power' campaign. 

The label is getting on board with the foundation's 'Girl Up' movement, which aims to empower teenage girls to become a force for change via community changes covering education, health services and personal safety. Over the next few years, the brand will create and launch exclusive capsule collections and specific campaigns in partnership with the organization, in order to inspire young women in various communities to "realize their best selves."

"I dream about a day where women everywhere are able to live their most empowered, most fulfilling lives," said the Hollywood actress and entrepreneur in a statement. "And the best place to start is with girls because they represent tomorrow's leaders, change-makers and innovators."

Launched in 2010, 'Girl up' focuses its efforts on helping those living in developing countries and areas where it is more difficult to be a young woman than others. There are now 1,200 Girl Up Clubs in 66 different countries, with high-profile advocates including Queen Rania Al Abdullah of Jordan and Latin American business leader Angélica Fuentes.

Hudson founded Fabletics in 2013, with the aim of offering high-quality activewear for women at an accessible price point, and the brand has since grown rapidly to include more than one million member customers from across eight countries.
