Nick Reiner was an unsolvable dilemma for his parents … so says a substance abuse treatment expert.

Nick Mathews — the founder and CEO of Southern California-based treatment center Stillwater Behavioral Health — joined us on “TMZ Live,” and we asked him about Rob Reiner and Michele Singer Reiner‘s son, who is charged with their murders.

For Mathews, Nick presented a treatment provider’s worst nightmare … he was diagnosed with schizophrenia, but had been in and out of rehab for years and struggled with substance abuse.

Just listen to Mathews explain all the challenges Nick would present for the rehab centers and doctors tasked with treating him … there’s no quick, easy fix or even a cut-and-dry solution here.

Former NFL player Myles Jack was arrested after a bizarre incident at a home in Texas on Tuesday … when cops say the linebacker broke out of a second-story window and fell to the ground before being taken into custody.

According to the Frisco Police Department, officers responded to a welfare concern around 5:40 AM … and when they got to the scene, gunshots were heard inside the residence.

Officers established a perimeter and evacuated other homes in the area … and said at one point in the incident, they observed a man later identified as 30-year-old Jack break a window, climb out, and plummet to the ground.

Jack is being charged with “deadly conduct – discharge of a firearm,” a third-degree felony … and “discharge of a firearm in certain municipalities,” a misdemeanor.

Barack Obama let that prima donna spice up his life this year — the 44th president revealed his favorite music of 2025 … and none other than BLACKPINK was in ink!

“Jump” by Jennie, Jisoo, Lisa, and Rosé popped up near the top of Obama’s official playlist for the year … so it’s safe to say he’s the newest member of the BLINK fandom!!

Either that, or Barry O fell victim to Diplo‘s production on the track. Regardless, it’s a big deal for the genre … as it marks the first-ever K-Pop song to be recommended by the former commander-in-chief.

The high-paced and confident single was released in early July and fed the appetite of hungry Blinks who craved new music after the foursome went on hiatus in late 2023.

BLACKPINK weren’t the only mega-sensations to land on Mr. President’s top-bops … Lady Gaga‘s “Abracadabra,” Kendrick and Sza‘s hit “Luther,” Chappell Roan‘s “The Giver” … and Drake‘s “Nokia!” made it — and made it big!
