Sienna Miller tattoo
's wrist is home to a flying swallow, which is a symbol of acceptance from the Primrose Hill set, confirming she really is an 'it' girl.
Other well known celebs that also have the exact same swallow inking are British stars Kate Moss
and Robbie Williams, which suggests they have a position in this exclusive social circle.
We're tempted to get one - just to be a part of the cool club.
Sienna is a fan of small and dainty tattoos - she also has a tiny tatt of three pale blue stars on her shoulder, and one a lone-star based near her belly button. Stars for a star - naturally.
