Now, new fuel has been added to the fire, after Lady Gaga opened up about their very public spat during an interview with USA Today.
Regarding her accusation that he was stalking her, Mother Monster elaborated, saying, "It's fine to hate me afar. Everyone can hate me from afar. But the second you try to move in next door to me, I know you're getting too close, and it's not safe. Already it's stressful not feeling safe as it is... If you hate somebody and you want to move next door to me, the only thing I can think of is that you're moving in because you want to blow yourself up."
Obviously, this didn't sit well with the celebrity blogger, who once again took to Twitter to defend himself.
"I've got my son and mom here with me in NYC and you think I'm going to blow myself up? Stop doing drugs!!" he tweeted, along with a link to the article.
He also took things a step further, tweeting at Gaga's father, Joe Germanotta, crossing the proverbial line by writing, "If your daughter ends up dead it's from a drug overdose. Not cuz I blew us up!"
Perez then concluded with a more general statement, writing, "If you think marijuana is the only drug @LadyGaGa has been doing regularly in 2013, then you're as delusional as she is."
We get it, Perez is REALLY hurt by what Gaga said (and vice versa), but do you think he took it a step too far with what he wrote to her dad?
Whose side are you on in this feud?
