The three are in the Italian capital for billionairess Petra Ecclestone's wedding on Saturday, so to kill some time they stopped by the Dolce & Gabbana boutique.
Their shopping trip was apparently a success because once they were done Paris tweeted:
"Just got back from shopping in town with @NickyHilton anf Fergie. We went to Dolce & Gabanna and got so many amazing things. Love Italy!"
Wonder if they made purchases for themselves or the bride???
