She made joint appearances with the All American Rejects (The Wind Blows) and Cassandra Steen (Never Knew I Needed) and finished together with her partner Niklas Dennin to earn second place in the final.

After Popstars, Demirezer reinforced her internet presence on Facebook and YouTube by introducing her own songs, which were mainly in German language.

On 7 April 2013, Demirezer joined Seeed, Blumio, Glass Bead Game and Andreas Bourani at the memorial concert in Admiral Palace "I Am Jonny – Voices for Our Brother" commemorating the murder of Jonny K. In early August 2013, a single entitled "200 Days Summer" was released.

The video, which shows Demirezer along with tame elephants on the island of Sri Lanka, was directed by Justin Kruse, who worked with Ivy Quainoo, Max Herre, Max Prosa, Leslie Clio and Joy Dena Lane on previous productions.

It was produced by Demirezer herself and Philipp Schwär and reached number 23 on the German album charts.
