Britney Spears to duet with Lady Gaga?

Britney Spears wants to work with Lady Gaga but she’s not getting her way.

Sources close to Britney say the controversial pop princess has become obsessed with Gaga, who before fame, wrote three songs for her.

“Britney is desperate to work with her again. She is very aware of that Gaga is a big threat to her in terms of her longevity in music,” reveals one insider.

“She’s fascinated with her and blown away by her music. So far there has been no indication that a collaboration will ever happen.

“Britney feels like with artists like Gaga and Katy Perry, her days in pop are coming to an end.”
