There seems to be a rash of female educators accused of having sex with their underage students across the U.S. — and there doesn’t seem to be any end in sight.

In the latest case, Dr. Keiva Lark — the assistant principal of Lake Marion Creek Middle School in Polk County, Florida — was charged Thursday with lewd/lascivious conduct and lewd offense against a student by an authority figure.

According to police … the 13-year-old student was sent to Lark’s office after tossing crumpled-up paper across a classroom during an exam.

Cops say a witness overheard Lark chastising the boy for falling down on the job before showing him how to do a proper foot rub … by allegedly giving him a shoulder and arm massage.

The witness told police they heard Lark tell the boy to rub her as if he loved her … and that she was teaching him these lessons for when he snags a girlfriend.

Days later, cops say, the witness reported the incident, and police launched the investigation on April 4. After her arrest, Lark was placed on administrative leave from the school.

Cain Velasquez was recently moved into his new home for the foreseeable future — Wasco State Prison — where he posed for a brand new mugshot … which TMZ Sports has obtained.

Velasquez, 42, who was sentenced to five years in prison for attempted murder on March 24, was transferred from the county jail near San Jose to the Cali state prison in Wasco.

When the UFC legend arrived, prison officials ordered Velasquez to pose for another mugshot … and he appears serious and stoic.

The pic was snapped just over three years after he was first arrested (and stood for a mug) for attempting to shoot a man named Harry Goularte.

Goularte is accused of molesting one of Cain’s family members … and is himself due in court this year, where he’s facing serious criminal charges.

Cain expressed remorse in front of a judge before sentencing in a courthouse late last month … saying he understood he screwed up, and would do all he could to make ammends.

It must’ve worked … ’cause Velasquez, who was facing decades behind bars, received a five-year sentence … in spite of Goularte’s relatives asking for more serious time.

Benson Boone has a special guest for his set at Coachella … and it’s Queen guitarist Brian May!!!

Our sources tell us Brian will join Benson onstage at some point during Benson’s Friday night set at the famous music festival.

Benson and Brian have boots on the ground in the desert … we obtained a photo of them getting off a private jet at the Palm Springs private airport earlier Friday morning ahead of their collab performance.

Benson’s drawn comparisons to Freddie Mercury, so a collab with Queen’s guitarist and backup vocalist makes a lot of sense … though it’s unclear what songs Benson and Brian will perform together.

Benson is scheduled to take the main stage at 7:05 PM PT for an hourlong set … and this will be Brian’s first time at the famed music festival.
