Is this a publicity stunt for Christina Aguilera who has been receiving mixed, but mostly bad reviews, about her latest come back? The two have been spotted on numerous occasions leading up to the release of Christina's latest album 'Bionic'. On the flip side, Kim could be using Christina to become even more famous. Kim is known to have a lot of friends in the industry. She has been linked to Lala Vasquez, Kelly Rowland, Ciara and a few other it-girls.
