In late 2008, she hosted (together with Peter Jihde) the TV400 program Idol: Eftersnack, a weekly sister program to Idol 2008 that featured interviews with the contestants and the jury. Zytomierska was heavily criticized in the Swedish media for making negative comments towards the contestants, such as calling one of them "too gay" and another one "gross" for performing barefoot. It was speculated that she would be forced to leave the program before the season ended; however, after an emergency meeting between TV4 and TV400, it was decided that she would be given a second chance.

During 2009 and 2010, she appeared frequently on the morning radio show VAKNA! med The Voice (which airs on The Voice, but is also televised on Kanal 5). Her controversial attacks on Swedish celebrities on the show made headlines in the Swedish media.
In September 2010, just before the 2010 Swedish general election, the news site Résumé reported that Zytomierska was being paid to promote the Moderate Party on her blog.
