The Georgian group Stephane & 3G (3 Girls) was chosen ahead of nine other acts in Tbilisi on Wednesday to represent the country at the popular annual music contest, in which 51 countries compete.
Stephane & 3G's song is entitled We Don't Wanna Put In, an obvious reference to Russian Prime Minister Vladimir Putin.
Georgia and Russia have had no diplomatic ties since last summer, when the two countries fought a five-day war and Russia recognized two Georgian republics as independent.
Moscow is hosting the event for the first time after Russian Dima Bilan won last year's contest in Belgrade with his song Believe. The semifinals are scheduled for May 12-14 and the finals will be on May 16.
The Georgian entry will not be the first time a former Soviet republic has mocked Russia on the Eurovision stage. In 2007, Ukraine's Andrei Danilko, who cross-dresses as an overly busty woman with the stage name Verka Serduchka, sang Lasha Tumbai, but intentionally slurred the words so that viewers heard "Russia Good-bye!"
The contest has been broadcast every year since its inception in 1956 and is one of the longest-running television programs in the world. It is also one of the most-watched non-sporting events, with international audience figures in recent years reported as anything between 100 million and 600 million.
