A medical scare briefly stopped the show at KROQ’s Almost Acoustic Christmas when All-American Rejects frontman, Tyson Ritter, abruptly cut the band’s finale mid-song to help a fan who collapsed in the crowd.

TMZ has obtained video showing the band halfway through “Gives You Hell” inside the packed L.A. Kia Forum, when Ritter suddenly halted the music, grabbed the mic, and pointed toward the pit, alerting security that a woman had passed out and needed help.

In front of thousands, Ritter calmly told the crowd to open space and assist her, then added a little holiday improv, urging someone to get the woman “Twinkies or sugar or Christmas gumdrops or pieces of gingerbread houses” to help her. Ritter also called out, “Are you okay?,” checking on her from the stage.

The emergency became one of the night’s unexpected highlights at the annual holiday concert, which delivered a stacked lineup featuring Third Eye Blind, Evanescence, Papa Roach, Yellowcard, Social Distortion, and Rise Against.

Cena locked horns with Gunther for his final match ever in the ring at Main Event in Washington D.C. on Saturday night.

A DoorDash driver was arrested after investigators say she deliberately pepper-sprayed a customer’s fast food order … an incident caught on video that left a couple choking, vomiting, and terrified over what they had eaten.

Kourtney Stevenson was cuffed Friday and booked on charges including consumer product tampering and battery resulting in moderate bodily injury. According to the cops, Stevenson was working a late-night DoorDash shift in Indiana when she allegedly contaminated an Arby’s order moments before dropping it off.

One of the victims says his wife took a few bites before suddenly gasping for air and vomiting, prompting him to check the bag where he spotted a strange residue.

Stevenson was quickly located and arrested. Cops say she later claimed she was actually spraying a spider, but investigators didn’t buy it, noting spiders don’t wander around in 35-degree weather.
