Czech Republic chose their entry to the Eurovision Song Contest 2008 through a national final, Eurosong, on 26 January 2008. Česká televize internally selected 10 acts to compete in the show and officially presented them at a press conference on 3 January 2008: three of the acts: Gipsy.cz, Sámer Issa and L.P.B., had competed in the Czech Republic's Eurosong 2007. On the same day, SMS numbers for the participating songs were revealed and the voting was opened. On 26 January 2008 Tereza Kerndlová won the Czech final with the song Have Some Fun. Tereza is a young singer and was part of the group Black Milk.
Tereza Kerndlova was a special guest at the Ukrainian nation selection, where she promoted the Czech entry. Since Czech Republic had come in 28th in the semi-final of the Eurovision Song Contest 2007, Tereza was obliged to perform her song in one of the two semi-finals of the 2008 contest. The EBU split up countries with a friendly voting history into the two different semi-finals, to give a better chance to other countries to win. On 28 January 2008, the EBU held a special draw which determined that Czech Republic would be in the second semi-final, held on 22 May 2008. The Czech Republic took part in the second semi-final on 22 May 2008. She placed second-last, getting nine points: five from Macedonia, two from Croatia, one from Malta and one from Turkey.
