Clubhouse entry as guest on a 'G' reward ticket.

Have done a search, and I think I'm correct in the following scenario...
Myself and the boyf are off in Upper Class to New York in September and to Dubai in April. For New York we're both on rewards i.e. 2 x G tickets. For Dubai I'm on a J and he's on a G.
My assumption has always been that with regards to taking a guest into the Clubhouse, any Upper Class ticket entitles the holder to take in a guest. This covers revenue J,D,Z or a reward G. Can someone confirm this is the case? I'd hate to get to the desk and find it's only for revenue paying passengers.
Thanks for the help, and if anyone wants to come in, the details are in the itineraries forum [y]
Thanks,
David.
