Sharing multiple posts to his profile, the "Power" star slammed Lala and her relationship with Emmett -- hitting everything from the reality star's sobriety to how the couple got together. Fifty even insulted both Lala and her man's appearance.
Fifty opened his offensive by posting a photo of a news story presenting Lala's claim from "WWHL."
"What's wrong with this hoe," he captioned the screenshot. "now don't say she didn't ask for it when I start tripping."
The "In Da Club" rapper even took a shot at Kent's battle with alcoholism. (back in May, Lala confessed to Andy Cohen at last season's "Vanderpump Rules" reunion that she was drunk for "four days straight" while on a trip to Disney World with Emmett and his two daughters.)
"oh this bitch be drunk 4 days straight," he captioned a pic of an old report. "She must just be on some drunk hoe, I don't remember type shit."
He then added, "Have a drink, hit da powda, have a drink, hit da powda have a drink hit da powda 4 days straight."
Fifty continued to criticize Lala's sobriety by writing a fake conversation between him and Emmett.
Captioning a photo of Lala and Emmett in bed, Fifty wrote, "Randell: I'm sorry Fofty this bitch is drunk and high. I told her put that damn phone down she don't listen. 50:Shut the fuck up Randell."
Fifty ended his posts with the OG clip that ignited the feud in the first place. In a scene from "Vanderpump Rules," Lala recalled to co-star Stassi Schroeder about how she met Randall and immediately landed an acting role in one of his films, adding that he got her Range Rover the day after she let him "hit it."
"Then he falls in LOVE with the hoe, and they live drunk and high happily ever after," Fifty wrote alongside the video.
Not unlike when the beef first began, Randall's ex-wife, actress Ambyr Childers, chimed in on Fifty's disses of her ex and Lala.
"Oh boy...here we go again!" Childers wrote. "I need a glass of wine for this one."
Waiting for your permission to load the Instagram Media.
Fifty's Instagram slam session came less than one day after Lala stopped by "Watch What Happens Live with Andy Cohen" Thursday night, where she told the Bravo boss she had evidence to prove Fifty's ego was bruised following by their feud.
"I mean, I listened to 'In Da Club' on my birthday, so that was pretty lit," the 30-year-old makeup entrepreneur told Andy, appearing to have let bygones be bygones.
"What did you make of that whole thing?" Cohen couldn't help but ask. "And why did you delete all the pictures of you and Randall around that time?"
"You know, I feel really badly for Rand at times because he signed up to be a movie producer, and he just happened to fall for someone who's like very out there and outspoken," Kent replied. "So in the moment, I was like, 'F this, I'm not having pictures up for people to screenshot and send to me and write mean things.' It was just the heat of the moment."
"But the whole thing, you know, I think I really dinged Fofty's ego," she added. "In fact, I know that because I have a receipt to prove that, which I would never post because I ain't that girl. I ain't beefing unless I'm gettin' paid on 'Vanderpump,' yo."
When asked by Andy if she took some "pride" getting under Fifty's skin, Lala ecstatically replied, "Yes! I'm from Utah! And to think it's like, 'Tupac and Biggie, Lala and Fifty.' Like, what up, though?"
A thoroughly entertained Cohen pressed his guest about that statement. "Are you and Fifty just like Tupac and Biggie?"
"Not at all," she fessed up. "No."
Lala's co-guest, Kate Bosworth, backed Lala up for standing by her man.
"That is my man," Lala insisted. "I will rock with Rand 'til the death of me."
Well, it looks like Lala's allegiance to Emmett might be the only thing her and Fifty agree on.
