Lionel Messi and Kobe Bryant first faced off for Turkish Airlines last Christmas in a cute viral ad that saw the superstars compete to sign a little boy's autograph. This year, they're competing in the true spirit of 2013 -- with "selfies". The sports stars snap themselves in several exotic locations, such as the Red Square in Moscow; The Great Wall of China; the Maldives; Bangkok; and Mount Kilimanjaro -- all of which are destinations Turkish Airlines flies to -- before Messi finally gets photobombed by Bryant in Istanbul.

It's not only the stars who've gone global - whereas last year's ad was by local agency Alametifarika, the new work is by Crispin Porter & Bogusky The spot breaks on TV in the U.S on December 9th, as well as in over 20 countries and in more than 15 languages.
