BERLIN, GERMANY - FEBRUARY 01:  Ruslana Stepanivna Lyzhychko, also known as Ruslana, a Ukrainian pop star and winner of the 2004 Eurovision Song Contest, gives the peace sign as she arrives for a press conference on February 1, 2014 in Berlin, Germany. Ruslana, a vocal critic of Ukrainian President Viktor Yanukovych, has been active in the ongoing demonstrations in her country, originally sparked by anti-government protesters reacting when Yanukovych backed out of agreeing upon closer ties with the European Union, choosing instead to align the country closer with Moscow. Since then, the protests have turned violent, resulting in at least four deaths, and have called for the removal of Yanukovych from office altogether.  (Photo by Adam Berry/Getty Images)
