Rosie Jones is a topless model and recently, a picture of her in a red and white striped bikini has been shared through out the Twitter-verse... a lot... and it's been attributed to Katy Perry. Even die hard Katy fans were convinced it was Russell Brand's ex. Heck, it's been retweeted so many times it comes up as a 'top photo' when you search for Katy Perry. What do you think? Does it look like Katy Perry? We think it does!
