Her fans are devastated by the news
She tweeted that "it is officially my final week on #XAM" prompting reactions from her fans.
Siima has worked with Vision Group since September 2009 as XFM station manager and breakfast show presenter which she co-hosted with Rudende and Libolo.
In January, she was announced as the new editor for "Flair For Her" magazine, following the death of its veteran editor Keturah Kamugasa.
Ms. Sabiti clarified that she is not quitting the show but "senior management" is making critical changes and "I have been taken off".
"I'm not a quitter. I have not quit the show," she added.
"It's not the end of radio for me but this looks like the end for me on XFM"
Her exit comes months after her co-host, Rudende, quit XFM to focus on his other engagements, including a business show on NBS TV.
Siima's fans are devastated by the news of her exit.
