Phoebe's finally had her ears pierced - Does anyone know when she got them done?

Looking at some সাম্প্রতিক pictures of Phoebe from August this বছর (2010), I noticed that Phoebe now has pierced ears. If আপনি look at older pictures of her, from 2008 etc, আপনি can see that she didn't have them done back then - Even on really HQ pictures, there's no sign of any holes in her ears. So I was just wondering if anyone knew exactly when she got them done?

And, in case আপনি doubt that she really does have them done now, here's a picture from the Tomorrow, When The War Began premiere in Sydney on August 9th, where আপনি can see the earring hook actually going through the hole in her earlobe:
