How long will cream cheese icing keep?

[wastingaway]

I've made the orange cream cheese icing from Cupcakes from the Primrose Cafe book (yum), and it says to keep it in the fridge, but not how long it will last in the fridge.

Any ideas?

Presumably as long as the Philadelphia it's made from would last?

Should I just sniff it?

How long do you want to keep it in the fridge?

It'll be fine for a week at least...

That's good, thank you!

I made it Saturday and thought I'd use the rest on Friday.
