Madonna decided to use a more relevant superstar to gain more cheers at her show in Atlantic City. She decided to dedicate her son "Masterpiece," to Lady Gaga.

And she still seems to be intimidated by the Mother Monster. Madonna said before her song:

"I'm going to dedicate this next song … to Lady Gaga. You wanna know something? I love her. I love her. I do love her. Imitation is the highest form of flattery. But one day, very soon, we're going to be on stage together. Just you wait. You think I'm kidding? I love Lady Gaga."

Clearly beckoning a response, Madonna also previously covered Gaga's "Born This Way" which has been compared to "Express Yourself", Madonna's 1989 hit from album Like a Prayer.

Gaga responded and although she didn't mention Madonna by name, she dropped her music-writing age -"I don't even want to fight back because it's more important to me to keep writing music. Because that's really all I care about, is the music," she said. "Things are really different than they were 25 years ago, and that's what makes 'Born This Way' so relevant for me. We're socially in a different place and it's OK, we don't have to all slice and hate each other anymore."

Everyone should have listened to Elton John when he said Madonna's career is over.
