Kristin Davis on Motherhood

Last night at an event hosted by Vanity Fair and Italian clothing designer Ermenegildo Zegna to benefit Oxfam America, Kristin Davis revealed to ET how her experience with motherhood has been so far.

"I love it," said Davis, who adopted her baby daughter Gemma Rose this past fall. "The only challenge is getting out of the house…I knew this would be true but you're so attached and it's just so fun to be there that it's hard to go."

Davis, an ambassador for Oxfam—an international relief and development organization that creates lasting solutions to poverty, hunger, and injustice—was joined by Colin, Livia Firth and Italian fashion designer Anna Zegna who were co-hosting the event.

The Firths talked to us in detail about Oxfam as well as Livia's "Green Carpet Challenge," which is an initiative that intertwines glamour and ethics to raise the profile of sustainable style at the world's most high-profile red carpet events.

"Tonight, thanks to Livia and Colin and with the presence of Oxfam, I think that we're going to witness how you can be responsible, stylish, beautiful, but also respectful to what is surrounding us," said Anna Zegna.

President of Oxfam, Raymond Offenheiser, expressed the priceless advantage of having gracious celebrities like Davis and the Firths who are able to spread awareness on a larger platform than the organization would otherwise have access to.
