A TikToker who openly called for Elon Musk‘s assassination is feeling the heat — fast … ’cause it looks like an investigation against her might be in the works.

In Sarah C. Roberts‘ vid — reshared by X’s right-wing account Libs of TikTok — she not only threatened the billionaire with a throat-slashing gesture and explicitly called for his murder, but also casually admitted to skipping filing her taxes for years.

Sarah’s social media accounts have since been deactivated, but the damage may be done. With the video making the rounds online, it’s now on the radar of some powerful figures — like D.C.’s top prosecutor, Interim U.S. Attorney Ed Martin.

The one-minute video was a lot. Along with her throat-slitting gesture, Sarah bluntly stated, “Here’s my one thought. I mean, I have many thoughts. Elon Musk. Like, we need to ‘X’ him. And by ‘X’ I mean, formally known as assassination.”

Sarah also threw in some wild claims about the FBI not having enough people to investigate her, before casually dropping her tax-evasion confession.

She wrapped it all up with a chilling encore — “So, I’m gonna f***ing say it. Let’s assassinate some motherf*****s.”

BigXthaPlug — one of rap’s biggest rising stars — has been arrested on a marijuana charge in Texas … TMZ has learned.

BigX was arrested on Wednesday and is currently being held at the Arlington City Jail. He’s been charged with possession of less than 2 ounces of marijuana.

Arlington PD tells TMZ … around 12:05 AM local time, BigX was driving with expired tags and got pulled over by cops. The officer reported he could smell marijuana as he approached the vehicle and asked BigX and the passenger — Cleodist Landum — to exit the car.

22-year-old Cleodist — who appears to be BigX’s relative — had an active felony warrant out of Bexar County, Texas. When officers took him into custody and searched him, they allegedly found marijuana on him. He was booked into the Arlington City Jail on the warrant, as well as for possession of marijuana, and unlawful carrying of a weapon.

The rapper’s a proud Texas native, born in Dallas, not far from Arlington.

Kanye West doesn’t want to be in the middle of controversy … this time. The 21-time Grammy winner is adamant he is not willingly involved in Bhad Bhabie‘s dispute with Alabama Barker, calling it an “A.I. beef” after BB used his voice on a diss track.

Ye’s Tuesday night Instagram explanation came shortly after the “Hi Bich” hitmaker posted a clip of an alleged remix of her new “Ms. Whitman” diss track that includes a verse by him. “Ms. Whitman” already samples KW and Ty Dolla Sign’s song “Carnival” … but without Ye’s voice.

Kanye says he originally cleared the sample because he says he clears all sample requests … reasoning that “so many people try to stop me, they stop clearances.”

The rapper even claims to have talked to Alabama‘s dad, Travis Barker — the husband of his ex-sister-in-law Kourtney Kardashian — to clear things up.

He explains … “I just talked to Travis Barker, I would never be in the middle. I don’t even know what’s going on. I just got sent a song and asked if I could clear the sample.”

This is a huge blow to Bhad Bhabie, who was thrilled to have Kanye’s stamp of approval on her new song.

As fans heard, the diss track drags Travis and the Kardashians. BB twerks all over a  look-alike of the Blink-182 drummer and calls Kourtney “burnt out.” Furthermore, she claims Alabama is not as tight with the Kardashian clan as she claims to be, rapping … “stanky p***y got you kicked out the Kardashian house.”
