Jelena Tomasevic was born in Kragujevac on 1st November, 1983. She entered the world of music in a town where she finished Elementary School and Gymnasium. At the age of eight, she won the top award at the Children’s Music Festival Sarenijada, and three years later, she became the winner of the Yugoslav Children’s Festival.

After becoming a member of the Abrasevic Folklore Ensemble, one of the most successful ensembles in Serbia, her music career soared. She achieved tremendous results at the most prestigious festivals.In 2002, Jelena emerged on the Serbian music scene and her career as a pop singer started to take off. She won over the jury in the superfinal of the TV show "3K DUR" which was broadcast on RTS Three with the aim of promoting young talented artists. Later that same year, she was second at the Zrenjanin Festival and won the best novice award. She was the Serbian representative at the prestigious music festivals in Bulgaria, the Czech Republic and Belarus.

After this turning point in Jelena’s career, she made a huge breakthrough. In 2003, she competed for the first time at the Budva Festival and finished second at the prestigious festival Slavjanski bazar in Belarus. In 2004, she participated with great success in the Beovizija Festival. In 2005, she met Zeljko Joksimovic. She became a member of the Minacord Production Company. In 2005, at the Beovizija, Serbia's part of the federation's Eurovision selection, she sang the song "Jutro" (Morning) composed by Zeljko Joksimovic and written by Aleksandra Milutinovic and won the top award, however in a very controversial final she lost out to No Name, who went on to represent Serbia & Montenegro in Kyiv.

Later in 2005, Jelena sang the soundtrack to the film "Ivkova Slava" which was written by Zeljko Joksimovic. The film pulled in a record number of viewers. The latest collaboration with Zeljko has brought Jelena to Eurovision. Zeljko, who is one of Serbia's biggest music stars is no stranger to Eurovision, having written and performed "Lane Moje", Serbia & Montenegro's runner-up in the 2004 contest. He returned to the contest in 2006 as the composer of "Lejla", the Bosnia entry which finished 3rd in Athens. The lyricist of that entry was  Dejan Ivanović and once again the duo have termed up to write "Oro". On stage in Belgrade, Jelena will be accompanied by Bora Dugic one of the the greatest flauists in Serbia.

In February when Zeljko Joksimovic was announced as one of the presenters of this year's Eurovision Song Contest, there was considerable discussion around a potential conflict of interest, if "Oro" was choisen as the Serbian entry, however the controversy soon died out, and we another Eurovision first, with a presenter being directly involved in one of the competing songs. 

This year's Serbian entry has been one of the bookmakers favourites since it was selected and is also doing well on internet polls, although not quite as well as last year's Serbian winner which was the fan favourite before the contest in Helsinki.
