Lana Del Rey's song "So Legit" leaked online earlier this week and features some pretty harsh and seemingly direct jabs at pop megastar Lady Gaga.
"So Legit" could have been written as early as 2008 or 2009, according to reports. Whenever she penned it, Del Rey's sultry vocals are unmistakable.
As is the fact that she's laying into the "Born This Way" singer.
Many thought the two New York natives were close friends - and maybe they are, or were - but this paints the opposite picture to say the least.
"Stefani, you suck ... I know you're selling 20 million," Lana Del Rey sings. "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," she continues.
"Have we all gone Gaga crazy?"
If Del Rey's not referring to Lady Gaga (real name Stefani Germanotta), then Ray J's not talking about Kim Kardashian in "I Hit It First."
Gaga's legion of Little Monsters swarmed the "Video Games" singer's Twitter and Facebook pages, but neither singer has commented directly.
What do you think? Old feud? New one? Viral marketing?
