*Janet Jackson says she knew Lady GaGa way before everyone else caught on to the phenomenon, and would love to collaborate with her sometime in the future.

The singer tells Metro: “What I love about GaGa is her story, where she came from.

“Before she made it, before anyone knew who she was, I knew who she was and, to see her finally make it, I was so happy.”

She added: “If we were to work together that would be cool.”

Earlier this year, Jackson described GaGa as a “sweetheart” and praised her hard work but also urged the singer-songwriter to “slow down just a little bit.”
