‘Glee’ Guest Star Darren Criss is Here to Stay!

The Fox series’ co-producer, Twentieth Television, says Darren Criss and his character, prep school glee club member Blaine, will continue to appear on the show this season and that Criss could become a regular next year under a newly signed deal, Fancast reports.

The 23-year-old’s character was introduced last week as a mentor to Kurt (Chris Colfer), an out gay student who faces harassment at school. Criss and the glee club at his school performed a cover of Katy Perry’s “Teenage Dream” in that episode.

Twentieth Television says the cover scored the highest first-day sales for a ‘Glee’ track, with more than 55,000 downloads.

Twentieth Television says whether Criss’ character and Kurt become romantically involved has yet to be decided.
