You are a Paparazzi and are just see Victoria Beckham walking on the other side of the street. But you do not have your trusty SLR camera with you only your camera phone. Good thing to have in this situation is the 6X Telescope lens for mobile phones.

As you have to exchange the back-shell of your mobile phone with the one bundled to be able to mount the lens, it is not going to work with all mobile phones.
Only Nokia 6230 and 6680 mobile camera phones are supported at this moment.
Brando sells the Mobile Phone telescope lens for only $19.00.
