Megan Thee Stallion Mom's Cemetery Notifies Police Amid Nicki Minaj Beef

Megan Thee Stallion's beef with Nicki Minaj has taken an ugly turn -- cops are getting involved to protect her late mother's gravesite, this after doxxing by her arch-rival's fandom.

The Texas cemetery where Megan's mom, Holly Thomas, was laid to rest after passing away from brain cancer in 2019 -- tells TMZ ... they've notified local authorities and increased security personnel at their facility in light of the escalating feud.

What's more ... we're told PSC will continue to monitor the situation as they take all matters regarding safety and security seriously -- and lately, things have been getting too real.

They do add ... as of yet, thankfully nothing has happened to the gravesite, but they emphasize they're on high alert regardless.

The extra precautions come after some of Nicki's "Barbz" -- AKA, her army of fiercely loyal supporters -- first leaked the location of Holly's burial site on social media ... encouraging others to go and desecrate her grave as a way to get back at MTS for her OG diss.

It all kicked off last week when Nicki distastefully cracked a joke about MTS' mother on the streaming platform Stationhead. Her exact line at the time was ... "You better go conjure up your mother and apologize. That's disgusting." It seems some of her fans took that to heart.

No doubt, ya gotta figure that was particularly heartbreaking for Megan to hear ... as she's been super candid and emotional over the years about her mother's influence in her life.

Megan has also been very open about what the loss of her mom has meant to her -- and by all accounts, it's been very difficult ... something that's been well-documented and discussed.

Now, Nicki did later explain that she only took the shot at Meg's mom cause MTS was coming after her own family. In particular, MTS seemed to reference Nicki's husband, Kenneth Petty, in her new track "Hiss" -- making a "Megan's Law" reference that many interpreted as shade toward Petty's legal trouble.

So, tit for tat really ... many felt Nicki had just gone too far, and doubly so for any one of her supporters who was seriously considering heading over to Holly's grave.
