Someone submitted this topless picture of a girl with a swallow tattoo on her right boob and the girl is non other than
Christina Ricci.
I assume the tattoo artist took the topless photo for her collection and put it on a webpage as a reference of her work and someone then put the 2 and 2 together and made an easy ID with help of some other revealing pictures of Christina Ricci.
Here is Christina Ricci topless pic and few other pictures that were used for a positive ID. Vegas cover photo for the swallow boob tattoo ID and bikini photo probably because of the mole between her boobs.
