'Glee' guest star Darren Criss joins Fox show

LOS ANGELES – "Glee" guest star Darren Criss has turned a "Teenage Dream" into reality. The Fox series' co-producer, Twentieth Television, says 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. 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. Criss returns on Tuesday's episode of "Glee," which features guest star Gwyneth Paltrow as a substitute teacher. Twentieth Television says whether Criss' character and Kurt become romantically involved has yet to be decided. — AP
