Controversies Contestant Lisa Bund caused a controversy on 10 March when the headline of the German tabloid newspaper Bild read that she fought with bullying, and harassment by some of the other contestants. On 14 March, Bild Online reportedBild Online article about a loud argument between Bund and former contestant Tristan Iser, which happened to have also been filmed by a mobile phone camera.Video Bund stated in an online diary entryLisa Bunds online diary that she felt the video was "like a bad horror movie".

On 22 April, Bild announced that contestant Max Buskohl quit the competition due to RTL's rejection of his request to let his school band Empty Trash get a recording contract alongside him. Viewers had wondered about judge Dieter Bohlen's uncharacteristic behavior when he gave an extremely critical review of Buskohl's performance on 21 April. Buskohl is alleged to have said that Bohlen was antisocial, which explains Bohlen's negative reaction.

Contestant Martin Stosch, who was eliminated on 21 April, remained as a contestant despite being voted off the week prior, replacing Buskohl.Bild Online: "RTL wirft Superstar Max raus!" However, Buskohl's father Carl Carlton told Spiegel Online that his son already made his decision to leave on 19 April but waited until Sunday to make his announcement at request of RTL.

Judges Dieter Bohlen and Heinz Henn had started a quarrel with each other during the show. On 14 April's show, Henn made it clear that he did not agree with contestant Mark Medlock's song choices. Bohlen, a staunch supporter of Medlock, began imitating Henn during his review of Lisa Bund's performance. Henn later stated that he thought it was "in bad taste, in bad style and disrespectful towards the contestants".Bild Online: "Fans toben: Bohlen hat ihn rausgemobbt!" / Extra – Das RTL-Magazin on 23 April 2007

On 24 April, German entertainer Stefan Raab announced a performance by Buskohl set for 25 April at his show TV total which at that time aired on RTL's rival television channel ProSieben. RTL pronounced against a performance by Buskohl and his band Empty Trash on TV total the next day. So during his show on 25 and 26 April, Raab publicly instigated a protest demonstration set for Saturday's Deutschland sucht den Superstar show and was said to have obtained about 120 tickets.Bild article about Stefan Raab and Max Buskohl However the show eventually went off without any disturbance.
