To say these pictures show a full-on Sienna Miller nipple slip would be a bit too strong a claim, however, she was caught at just the right angle, and if you look closely, you can see some Sienna Miller nipple action.
Of course, it's nothing compared to the time we saw Sienna Miller topless, or the other time we saw Sienna Miller topless, or even the other time we saw Sienna Miller topless, but beggers can't be choosers.
Oh, Sienna also has a nice ass. Bonus.
More Sienna Miller pics after the jump.
