Katy Perry was totally on board when Darren Criss (Blaine) led the Warblers in “Teenage Dream” on Glee, but how did she feel about the Cheerios covering her smash hit “California Gurls”? Judging from her Twitter account, pretty darn good.
"#GLEEEEEEEEEEEEEE #WEEEEEEEE!" she tweeted Sunday night during the telecast. Looks like someone was excited. And using hashtags.
