Was Lady Gaga mad about her episode of Glee?

When the cast of Glee spent much of an episode singing Lady Gaga's songs like "Bad Romance" and "Pokerface" and dressing up in outrageous costumes to imitate the superstar, Gaga fans held their breath that she wouldn't get offended at all the theatrics. As it turns out, Lady Gaga was thrilled! "I went to a musical theatre school and used to dream that someday the students would be singing my songs."
