Over the past few weeks, we've seen a lot of feuds between celebrities erupt in the Twittersphere. Tomi Lahren called out Taylor Swift, Conor McGregor taunted recent match rival, Khabib Nurmagomedov, and let's not even start on the whole Cardi B/Nicki Minaj drama.
Yesterday, though, all the focus was on two people: Lana Del Rey and Azealia Banks.
Once upon a time, the two musicians got on pretty well - but that all seems to be in the past now.
The tipping point in their relationship was Lana's comments about Kanye West. Last week, she put Ye on blast, and criticised his support for Donald Trump in a scathing Instagram post.
"Trump becoming our president was a loss for the country but your support of him is a loss for the culture," she wrote.
"I can only assume you relate to his personality on some level. Delusions of grandeur, extreme issues with narcissism - none of which would be a talking point if we weren't speaking about the man leading our country."
But Banks took issue with Lana picking on West, accusing her of "pretending" to be an ally.

The Big Big Beat artist then went on to say that Lana had only picked on West because he is a black man and that she, as a white woman, would automatically receive more support because of that.
"You would never in your white mind try to battle ME on my ideas," she said. "I suggest you apologize to Kanye for trying to selectively make him complicit in 45's abuse of women simply for agreeing with parts of his ideology while you frolic through society with other black male abusers like ASAP Rocky."
For a week or so, it looked as if Lana was just going to ignore the tweets. Yesterday, however, she snapped.
"U know the addy. Pull up anytime. Say it to my face. But if I were you — I wouldn't," she tweeted in reply.
Then, she wrote: "I won't not f**k you the f**k up. Period," followed by: "Banks. U coulda been the greatest female rapper alive but you blew it. Don't take it out on the only person who had your back."
The Video Games singer then went for a low blow as she tweeted, "I'll send you my surgeon's number and a good psychiatrist I know in LA - your psych meds aren't working."
Azealia had the last word in the spat, however.
"Should I be extra white woman and sue Lana for threatening me? I thiiiiiink soo," she joked.
Lana seems to have left the argument for now but, considering she waited more than a week to hit back the first time, we're willing to bet that this spat is far from over. Meanwhile, Azealia seems to hope that she will be moving on and making music with Kanye soon - and you can bet there will be a few harsh words against Lana if that ever comes to fruition.
