Hadise Açıkgöz, commonly known as Hadise, was born on October 22, 1985 in the small Belgian town of Mol outside Antwerp and is the second daughter in her family from Sivas, Turkey.

After completing her secondary education, she began working in various jobs to support her family. While she was working to support her family, she completed her degree in marketing at the university. Hadise had only one dream: To be a world star.

Hadise recalls her dream stating, "I have always wanted to sing as far back as I can remember. I wanted to go on stage. I would make short dresses out of my sweaters, grab a hairbrush for the mic, and would pretend to perform in front of my mirror. I knew that I wanted to be a singer. I wanted to travel the world and share my experiences, my music, and my voice with everybody." 

She stepped onto the music scene in 2003, appearing in the first season of Idols 2003 singing competition in Belgium. Although she was invited to the auditions and received positive praise from the panel of judges, she didn't make it to the finals.

Six months later, she was approached with an offer for her debut album and accepted it. She signed an album deal with 2 Brains Records, worked with Yves Gaillard for her first single "Sweat," and released it on November 1, 2004.

The single peaked at number 19 on Belgium chart Ultratop. After the success of her debut single, she released her debut album also titled Sweat, and her second single "Stir Me Up" in November 2005. After her second single reached the 22nd spot on Belgium charts, Hadise also started getting recognition in Turkey. "Stir Me Up" was among the most listened-to songs in Turkey during the summer of 2005. Her third single, "Milk Chocolate Girl" peaked at number 13 in the Belgium Ultratop 50 and became Hadise's most successful single to date. In Belgium, Hadise was nicknamed after the song's title "Milk Chocolate Girl," which helped her reach mainstream appeal.

Her first concert in Turkey was in 2006 at Club Loop in the coastal city of İzmir. Hadise, who frequented Turkey that year, also participated in many TV shows and other events. 

In September 2007, she released her first single, "A Good Kiss," off her upcoming self-titled second studio album. The music video was filmed in Istanbul and the song made a big impact in Turkey and Europe.

"My Body," the second single off the second album Hadise, continued her rapid ascension by reaching the eighth spot on the Belgium Ultratop 50 on February 23, 2008, and it was the highest entry of that week. 

Her second album Hadise and was released in June 2008 with 16 tracks. Hadise co-authored the lyrics for ten songs on the album with Yves Gaillard. There were two Turkish songs on the album with one titled "Deli Oğlan," the Turkish version of "A Good Kiss." The singer, songwriter, and producer Sezen Aksu wrote the Turkish lyrics for the song, and the music video was shot by Emir Khalilzadeh. The song was quickly reached the top spot on all the music charts in Turkey.

Most people in Turkey wanted to see Hadise perform at Eurovision that year after the success of the song, and Hadise represented Turkey in the Eurovision Song Contest in 2009 after being selected by the national public broadcaster TRT. Hadise prepared three songs for the Eurovision competition and presented them to TRT. TRT selected "Düm Tek Tek" among the others and asked her to perform this song at Eurovision 2009. Hadise debuted the song in her live performance on a nationally broadcasted New Year's Eve program to open the 2009 New Year, which was the top-rated program that night.

During the Eurovision 2009 semifinals in Moscow on the night of May 12, Hadise came onto stage to represent Turkey, which was in ninth place, and she qualified for the final round with 172 points. On the night of May 16, she represented her country, which was in 18th place, and she came in fourth with 177 points. She was the contestant with the highest number of votes in Eurovision for their country with a 204-point when the jury votes removed.

Hadise remarked on the contest stating, “I always said I would be in the top five, and I came in fourth. I am proud of it. I achieved my goal. I never aimed to come in first, because the final round was tough. While I'd have liked to come in first, I didn't push for it and instead, prayed to be in the top five. God accepted my prayers. When I heard the results, I wasn't disappointed. I was glad and relieved."

"Düm Tek Tek" became a big hit not only in Turkey but also in many other countries around the world. The song reached the #1 spot on the Belgian Flemish Chart (Ultratop 50) and stayed there for three weeks. It reached the 24th spot in Belgium's Wallonia (Ultratop 40), 2nd on the Greek Billboard, and 12th on the Swedish Singles Chart. The song also entered the UK Singles Chart at #127 on May 30.
