Paris Hilton, Nicky Hilton Mac Store Beverly Hills blonde sunglasses

Paris and Nicky Hilton stopped by the Mac store in LA on Friday evening, and that wasn't the only stop they made! After hours of Black Friday sale shopping (huge!), Paris tweeted, "Just finished shopping with @NickyHilton at Barney's, Intermix, Mac and Burberry. Got so many beautiful things, loves it. :)"

So here's what we want to know ... what will Paris' boyfriend Cy get her for Christmas? The heiress slash entrepreneur already has everything a girl could possibly want, so maybe something sparkly and set in gold?
