Connecting people xD

Here's a game I saw on the internet somewhere.. thought it was funny for this forum too =)

I say a the name of a person and then you say the name of a person that works together with him or something like that..

example:

Britney spears --> Justin Timberlake
Justin Timberlake --> Cameron Diaz
etc. =P
I'll start with

Christina Aguilera
