Lady GaGa was to open for Michael Jackson’s 'This Is It' show

Lady GaGa was due to open with Michael Jackson at his ill-fated This Is It comeback shows.

The King of Pop died last summer (Jun 2009) after suffering a cardiac arrest just weeks before he was due to begin his 50-date residency at London's O2 Arena.

And now, GaGa has revealed that she had agreed to be one of Jackson's warm-up acts, and was even hoping to perform onstage with him.

"You know, it's always very difficult because I don't necessarily like to talk about those very personal things that happened. But I guess I can speak about it now. I was actually asked to open for Michael on his tour. We were going to open for him at the O2 and we were working on making it happen. I believe there was some talk about lots of the openers doing duets with Michael on stage,” the Daily Express quoted her as saying in a pre-recorded chat with U.S. talk show host Larry King.

"But Michael's death was devastating for me regardless of whether or not I was supposed to go on tour with him. He's such an inspiration and a remarkable human being,” she added.
