post to website from facebook

Hi all,
Im not sure if this can be done, but ill ask anyway, I know i can post to facebook automatically when i publish a post from my website but what my client has requested is can we post to the blog from facebook (effectively reverse the usual) im sure there is a way to do it (im not very good with code) but maybe somebody knows about a plugin that can be used
im using moesia theme by vladff and jetpack plugin for the social media sidebar.
