Oh no she didn’t! LANA DEL REY drops  DISS track on ex- BFF LADY GAGA and tears her a proverbial new one!

Lady Gaga and Lana Del Rey shared a lot in common- including the same manager, Bob Leone, in the early days and played many of the same seedy locales as they hustled their way to the top.

But now, it seems, their friendship is over. Or it will be once Gaga hears Lana’s new track, So Legit, which eviscerates the Born This Way singer.

The newly-leaked song includes brutal, personal lyrics about Gaga, born Stefani Germanotta.

“Stefani, you suck,” one line reads. “I know you’re selling twenty million. Wish they could have seen you when we booed you off in Williamsburg.”

“You’re looking like a man, you’re talking like a baby,” Lana sings. “How the f*** is your song in a Coke commercial, crazy? I don’t get it. Your taste once so exquisite … How the f*** would you go switch it up and then replace me?”

She asks, “Have we all gone Gaga crazy?”

Take a listen and decide for yourselves.
