Gaga and Brit to Make Music?

According to Star magazine (title-linked), the new princess of pop Lady Gaga plans on singing a duet with former pop princess and huge comeback star Britney Spears after Gaga's Monster Tour finishes. Lady Gaga's father Joseph (presumably her manager or agent) exchanged phone numbers with Britney to schedule a meeting in the studio. Gaga wrote the new hit Beyonce song "Telephone" for Britney but at the time Britney rejected the tune. However, this does not upset Gaga as she loves the song and she gets to perform it now. Maybe because Gaga is such a hit, Britney is turning around?
