Who Was The Third In The Christina Aguilera Sam Ronson Threesome?

Samantha Ronson has said she has not had sex with Christina Aguilera, but Sam's music producer begs to say otherwise. In an interview with The Sun, Marlon David said that in Mexico for Nicole Richie's bachelorette party that Christina and Sam hooked up and did so with a third person. There were not that many women at the party, so I wonder who it could have been? Was it a member of the party or did the women find someone random from the streets of Mexico? Who was this third person?

"Sam said she had a threesome with Xtina in Mexico last month, that's when she realised she was a 'hot piece of ass'. Sam said Xtina is 'horny as a college freshman'."

Marlon also said that Christina gave Sam a Skype peep show after they got back from Mexico.
