New 'Glee' teaser video features pink-haired Dianna Agron and cafeteria food fight

Fox has released a new promo video for Glee's upcoming third season.

The clip, which appeared online Thursday, shows scenes from the new episodes which tease potential plotlines for each character.

Quinn (Dianna Agron) is seen sporting newly-dyed pink hair while Cheerios coach Sue Sylvester (Jane Lynch) has gold glitter poured over her head.



Will Schuester (Matthew Morrison) and Emma Pillsbury (Jayma Mays) share a quick kiss and the glee club members are also seen at the centre of a food fight in the McKinley High cafeteria.

Several cast members have expressed their hopes for the upcoming season of Glee, with Lea Michele admitting that she would love her character Rachel Berry's gay dads to be introduced and Chris Colfer keeping his fingers crossed for a continuing romance between his Kurt and Warblers singer Blaine (Darren Criss).

Lynch, who will host the upcoming Primetime Emmy Awards, recently hinted that the Glee cast may perform during the ceremony.

Glee returns to Fox on Tuesday, September 20.
