Looks like Sienna visited some hindu temples and took part in a prayer ceremony whilst in india because she is wearing a sacred red thread known as mauli.....which is tied on those taking part in prayers...to symbolise the receiving of blessings
I just hope people don't see it as a fashion thing and start tying red thread on their wrists for the sake of it!![]()

hahahait really looks like that pot is a hat or something.

i thought it was a hit first, just very bad placed on her head
