Is it safe to have Internal DNS Master have NS records point to DMZ Server?


I have three internal DNS servers, 1 master and 2 slaves, and three DMZ servers, 2 masters and 1 slave. The internal master currently has two NS records pointing to the 2 DMZ Masters. Is this a safe practice? Should I change them to point to the 2 internal slave servers? Is there a limit to the number of NS records?
Thank you for any feed back.

The DMZ server should really only host Internet facing zones - e.g. mycompany.com. The internal name servers should be authoritative for internal domains (e.g. mycompany.local) and possibly operate as caching servers for external lookups. However this is not the only way to architect things, bind supports 'views' which allow you to provide access to different information based on where the client request is coming from.
