Grimes has called out her ex-husband Elon Musk after he took their four-year-old son into the White House.
The SpaceX and Tesla CEO just can't seem to stay out of the headlines at the moment.
Musk was the centre of controversy at President Donald Trump's inauguration last month, as he was seen doing a 'Nazi gesture' up on stage, which Grimes also commented on.

The South African-born tech entrepreneur has been a huge supporter of the 47th US President, and he's one of his closest allies, as he was part of an Oval Office press conference at the White House yesterday (11 February).
Musk wasn't alone though, as he brought his son along.
X AE A-XII, better known as X, could be seen sitting atop Musk's shoulders as the tech CEO was asked about the United States Agency for International Development (USAID).

His son, whose name is pronounced 'X Ash A Twelve', could be seen looking bored and uninterested as his father answered a number of questions from reporters.
One of the questions Musk was asked about pertained to rumours that $50 million (£40.1 million) worth of condoms was being sent to Gaza in Palestine, though the reporter corrected this claim to be the Gaza Province in Mozambique.
The purpose of the move was to protect people from HIV, according to the reporter, but Musk stated that sending that many condoms anywhere wasn't the best idea, adding: "That's really an enormous number of condoms, if you think about it."
While his answer garnered some laughs from the press on Tuesday, the mother of his son, Candian singer Grimes, was not happy with X's public appearance.

Taking to social media platform X, she wrote: "He should not be in public like this. I did not see this, thank u for alerting me. But I'm glad he was polite. Sigh."
The 'Oblivion' singer was responding to a post from a user that called him 'polite' and 'cute', as he told the President, 'please forgive me, I need to pee'.
Grimes, whose real name is Claire Boucher, has so far not spoken too much about Musk's role on Trump's team, though she addressed his 'Nazi gesture' by mentioning that she was 'happy to denounce Nazi-ism', saying that she needed to think 'diplomatically' before saying anything further.
The 36-year-old previously said of Musk's public display of their son: "I have made it very clear I do not approve of that in every conceivable way I know how," adding that it's a 'personal tragedy of mine'.

Grimes also previously wrote online that she just doesn't 'wanna be deported haha - like literally', when speaking about some of the new bills being put in place.
Musk and Trump were in the Oval Office on Tuesday for the President to sign an executive order aimed at scaling back the federal work force, making agencies employ 'no more than one employee for every four employees' that leave, report Semafor.
Trump stayed quiet as Musk answered questions from reporters for about 30 minutes.
