We all know that Marshall Mathers, AKA Eminem, is not afraid of a little conflict in life.
In fact, the Detroit-born rapper seems to thrive off a little animosity, and over the years he's certainly been right at the centre of some of hip-hops biggest feuds.
Indeed, earlier this year alone, the rapper became embroiled in a bitter feud with Machine Gun Kelly, a beef that dated way back to some seriously ill-advised tweets Kelly purportedly wrote about Em's daughter Hailie.
Em then appeared to reference MGK on a track on his recent album, before Kelly responded with a dedicated diss track of the Lose Yourself star.
To no-one's surprise, Eminem came back swinging with his brutal response, Killshot, a ferocious tirade of ill-will directed at Kelly that lead many fans to pronounce MGK's career as finished.
Anyway, one of Em's more unlikely beefs comes in the form of a long standing dispute with the singer Christina Aguilera.
The feud dates back many years, but Em reignited the whole thing once more in his new 10-minute freestyle Kick Off.
The extremely NSFW lyrics read:
And, as you'd expect, a lot of people were very upset with Shady.
One wrote:
"Ya'll favorite rapper Eminem be out here dissing pop stars like Mariah Carey, Christina Aguilera, Jessica Alba, Britney Spears, J-Lo & wonder why we don't have him in our top 10 or 30. He's a cornball."
Meanwhile, a mother of one of the victim's of the horrific attack in Manchester at an Ariana Grande concert last year has criticised Eminem for referencing the incident in the same freestyle.
The Detroit rapper's lyrics read;
“Squashed in between a brainwashing machine, like an Islamic regime, a jihadist extreme radical, suicide bomber that’s seeing Ariana Grande sing her last song of the evening, and as the audience from the damn concert is leaving, detonates the device strapped to his abdominal region.
“I’m not gonna finish that, for obvious reasons.”
Mother Charlotte Hodgson, whose daughter was one of the 22 who were tragically killed that night, said;
“I didn’t think anybody could do this and be so disrespectful to us all. It’s vile and he is a vile human for doing it.
“Why would anyone compare themselves to a Jihadist or a bomber? I think he needs help if he sees himself like that.”
“Why would anyone want to listen to it for entertainment? Ariana did a very respectful song in memory of everyone there and that was lovely, a fantastic gesture, as she was involved too, but why would people want to make money out of such a horrific event?”
As usual, Eminem is courting controversy from almost every conceivable angle.
