"Glee" adds more characters in its sixth and final season. 

WetPaint reported that Blaine's (Darren Criss) mother will be introduced in the eighth episode of "Glee" season 6. Although the report did not mention a lot of information about the character, it stated that Blaine's mom "makes her living shilling Mary Kay cosmetics." She is also named Pam, as in Pam Anderson. 

There is no official news yet about who will play the role of Blaine's mother, but it is reported that the production is currently looking for the perfect actor to play the role of this colorful character.  While this would certainly be interesting for fans, there are also people who are wondering why the character needs to be unveiled this late in the series, since this will be the final season for the popular musical show. 

Meanwhile, singer-songwriter Billy Lewis Jr. verified that he will also join the stellar cast of Glee in its final season. In his own website, Lewis Jr. stated: 

Set your DVRs!!! SO STOKED to finally announce, I've been lucky enough to join the cast of 'Glee' for their 6th and Final Season!! It's been quite the whirl wind over the past couple months and I'm excited to keep sharing this crazy experience with everyone!! Tune in Friday, January 9th for the Season Premiere!!! Until then I'll keep the pictures & the news coming!" 

The singer did not reveal which role he will play in the upcoming season, but there are reports saying that he will be portraying a character named Mason, one of the five new members of McKinley High's New Direction. 

Also, Blues singer Noah Guthrie posted on his Facebook page that he will portray the role of Roderick, one of the new cast members on FOX's popular musical dramedy. His character will reportedly be the new underdog in the series. 

Other additional cast members are still unnamed as of the moment.
