@JasonTruluck & @stsd Thanks for your support.

I done this and I’m Using OmniAuth.

https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview

In my controller I define this

private

  def authentication_sign_in
    omniauth = request.env["omniauth.auth"]
    user = User.new
    user.apply_omniauth(omniauth)
    session[:omniauth] = {:firstname => user.firstname, :lastname => user.lastname, :email => user.email }
    session[:provider] = omniauth['provider']
    session[:uid] = omniauth['uid']
    redirect_to new_member_registration_url
  end

And In my Registration Controller

def new
  if session[:omniauth]
    resource = build_resource(session[:omniauth])
  else
    resource = build_resource({})
  end
  respond_with resource
end
