Roz was first introduced in Season 3 as the coach of McKinley's synchronized swimming team. She was later put in charge of the Cheerios when Sue was fired — causing obvious tension between the two tough women. In Season 5, Roz helped the cheerleading squad win first place at Nationals, and Principal Sue subsequently allowed Roz to keep her job. Leakes will appear in at least one Season 6 episode, which is set to shoot in early October.
The reality star-turned-actress, who also starred on Ryan Murphy's comedy The New Normal, joins previously announced returning guest stars Mark Salling, Dianna Agron, Jenna Ushkowitz, Jayma Mays and Max Adler.
Fox declined to confirm Leakes' return.
Glee's final season is set to premiere in 2015 on Fox.
