Sienna Miller and her sister Savannah were snapped this afternoon as they shopped around New York City together. We haven’t seen Sienna too often lately – and we never seem to get a glimpse of her with Jude Law. The two must be trying really hard to keep things very private this time around.

I love the expressions on their faces in these shots, it looks like they are sharing some “sisterly fun”. Sienna and Savannah have birthdays that are just two days apart. I wonder if their parents threw them a “joint” birthday all the time when they were growing up? Do you do that if your kids are born close to the same date to save on the cost of the party?
