It seems that Britney Spears is in a collaborating spree these days. Earlier this year, we heard that Spears is planning to team up with Rihanna for a duet and now it's Lady Gaga.
If grapevine, is to be believed then we might hear the two pop stars croon together in an album. But this not the first time, the duo would work together. Britney recorded Quicksand which was written by, poker face singer, for the deluxe edition of her 2008 album.
Last week Lady Gaga attended Britney's, Femme Fatale concert in Atlantic City and had immense fun backstage.
An insider told The Sun, "They sat for around an hour gossiping and talking about collaborating together on a track. Gaga already has two songs in mind."
