Britney Spears seems set to appear in an episode of the Fox musical-comedy television show “Glee” next season. Show co-creator Ryan Murphy said Tuesday he expects Spears to act in an episode that's “reverential about her.” Murphy said on Ryan Seacrest's radio show he admires how Spears has turned herself around. The singer spent years as tabloid fodder for a series of high-profile hospitalizations and erratic behavior such as shaving her head. On “Glee,” singers under anesthesia at the dentist's office hallucinate about Spears and being like her. The episode will feature Spears' music and won't delve into her personal life.
