LOS ANGELES (CBSNewYork/AP) — Kerry Washington, Lena Dunham, Emma Watson, Selena Gomez and Serena Williams say help from other women has been critical to their success.

The stars appear in a video released Thursday by LeanIn.org to promote its new “Together Women Can” campaign. Eva Longoria, newscaster Megyn Kelly and soccer star Abby Wambach also appear in the video.

Actress and UN Ambassador Emma Watson also makes an appearance in the minute-and-a-half long video, which debuted Thursday morning. Watson has become a rising figure in the women’s empowerment movement, serving as the ambassador for UN’s HeForShe program, which promotes gender equality.

The video shows each celebrity speaking of the women in their lives who have influenced them and how they celebrate female unity.

“Behind every successful woman, is another successful woman,” the video reads in its opening statement.

LeanIn.org founder Sheryl Sandberg said the campaign is meant to raise awareness of the ways that women can support each other in the workplace and encourage confidence and leadership skills in girls.

The video is among several set to appear on the campaign’s website, which also includes tips for mentors and guidance for modeling leadership skills for girls.
