The pair are ambassadors for the Lil-Lets 'We Are Women' campaign, which encourages ladies to be proud of their femininity while raising money for Jo's Cervical Cancer Trust.
The clip sees Faith and Van Outen talk about some of their favourite aspects of womanhood, such as becoming a mother and feeling empowered.
Both have donated personal items for an eBay auction in aid of the campaign, as have fellow female celebrities Tamzin Outhwaite and Lauren Goodger of TOWIE.
Van Outen, who put up for sale a Burberry Mac, said: "I'm very excited to be working with Lil-Lets on the 'We Are Women' campaign.
"It's a great opportunity for us girls to unite and celebrate all the great things there are about being a woman, whilst also raising money and awareness for a great cause that I'm sure has resonance with all women."
Explaining her donation of MAC lipstick and a Vivienne Westwood clutch, Faith added: "The 'We Are Women' campaign is the perfect excuse for British women to get together and embrace our femininity - discuss the things we love about being a girl and feel united in the things we don't.
"[The items] I've donated remind me of getting glammed up for a night out with my friends, which is one of my favourite things about being a woman."
