Grimes has begged Elon Musk to turn off his phone after he tweeted "pronouns suck".
The 32-year-old singer replied to her 49-year-old Tesla CEO partner with a pleading message after he posted his tweet.
In a now deleted tweet, Grimes wrote: "I love you but please turn off ur phone or give me a dall. I cannot support hate. Please stop this. I know this isn't your heart (sic)."
Meanwhile, Grimes and Elon welcomed their son X Æ A-XII Musk into the world in May.
The unusual moniker has sparked debate over pronunciation, and Elon previously broke down each element of his son's name.
He said: "It's just the letter X and then the Æ is pronounced 'Ash. A-12 is my contribution.... Coolest plane ever. It's pretty great."
He also explained that Grimes "mostly came up with the name," adding: "Yeah, she's great at names."
And the SpaceX founder even corrected Grimes' explanation of their son's name after she took to Twitter to explain its origins.
She wrote: "X, the unknown variable ... Æ, my elven spelling of Ai (love &/or Artificial intelligence) ... A-12 = precursor to SR-17 (our favourite aircraft). No weapons, no defences, just speed. Great in battle, but non-violent + (A=Archangel, my favourite song) (metal rat) (sic)."
However, Musk couldn't help jumping into the comments to correct his partner.
He wrote: "SR-71, but yes," in reference to the aircraft and it didn't take Grimes, 32, long to put him in his place.
She tweeted: "I am recovering from surgery and barely alive so may my typos b forgiven but, damnit. That was meant to be profound (sic)."
Elon quickly backed down and wrote: "You are a powerful [fairy emoji, queen emoji]."
