Uinterview - u ask. they tell.

Britney Spears, 28, may have been criticized in the past few years for her unintelligent decisions – a quickie Vegas wedding and annulment, shaving her head – but it seems the pop icon is turning herself around. Case in point: Making an appearance on Fox's hit show Glee was her brainstorm, according to creator Ryan Murphy. "Well, it's her idea. She sort of wants to do a 'Where's Waldo?'-type thing with 'Where's Britney?'" Murphy revealed while promoting his latest film Eat Pray Love.

Spears' manager, Adam Leber, began a Twitter campaign this spring to have a Spears-themed episode on Glee. "Do you guys want to see a Britney Spears episode of GLEE?'' Leber tweeted. Spears will be appearing in a season two homage episode, similar to the Madonna and Lady Gaga episodes in season one, though neither appeared in the actual shows. Murphy confirmed that while the Spears-themed episode is definite, it is not set whether or not the "Toxic" singer will make an onscreen appearance.

Brit has sold over 28 million records throughout her career and has had guest roles on a number of television series, including as a closeted lesbian on Will and Grace and as a receptionist on the critically acclaimed How I Met Your Mother.  –ELENA COX
