The singer/actress didn't get the chance to meet with the Paparazzi hitmaker during the creative process, but will finally come face-to-face with Gaga next week (begs09May11) when she makes a guest appearance on reality show American Idol, on which Lopez is a judge.
And Gaga fan Lopez can't wait.
She tells news show Access Hollywood, "I didn't (get to meet her) and I wish I could have.
"RedOne, who collaborates with her on a lot of her music, worked with me on this album. He played me different ideas and different things and one of the ones that I responded to, actually a couple of them, he was like, 'Just so you know, I worked with Lady Gaga writing those.' And I was like, 'Really? Is it OK if I do them and make them my own?' and he was like, 'Absolutely'. So I kind of lucked out."
