I am doing a complete bathroom renovation. I wish to install two GFI
receptacles in a double box. The incomming wire is always hot and
goes no further than the box in question. As there is already one
existing GFI recptacle in place i can see how its wired. can i just
pigtale its white and the new ones white to the incomming white and
pigtale the current black and the new black to the incomming black
and common the grounds

Why not install a regular (non GFI) duplex receptacle downstream of the
existing GFI?

Yes or you can do as Peter suggested to save a little on the cost of an
additional GFI. Put your pigtail wires from the second receptacle into the
LOAD terminals on the first GFI. That will make the second receptacle GFI
protected. The current code calls for a separate 20 amp circuit for the
bathroom.

This is excellent advice but you will need to use the decora style duplex so
that you can find a 2 gang cover to fit.

They actually make two gang Decora/Duplex plates, although a two gang
Decora/Decora plate would look more attractive
