Mark Labbett, the towering “Beast” of The Chase whose quizzer quips have quashed contestants for 15 years, unleashed a tirade that turned a dating show’s dream into a diva disaster. On June 11, 2025, during a grueling 11-hour shoot for E4’s Celebs Go Dating—where the 59-year-old quiz king hunts for love amid a lineup of love-lorn celebs like Kerry Katona and S Club’s Jon Lee—Labbett hit his limit, bellowing “I’d had enough!” before storming off set in a huff that left bosses scrambling and crew shell-shocked. “The Beast threw a strop and walked off as filming overran—he wasn’t happy,” a source spilled to The Sun, revealing how the marathon marathon of match-making mayhem pushed the trivia titan over the edge. “He made it clear he’d had enough and left filming altogether—bosses were panicking, everyone stressed if he’d return.” Labbett, fresh from a diabetes-fueled halt earlier in production (a hypo scare that paused takes), bolted after a day that dragged from dawn to dusk, his “beastly” behaviour a beastly blow to the show’s smooth sails.

The eruption? Epic. Subbed in as the “relationship expert” alongside Anna Williamson, Dr. Tara Suwinyattichaiporn, and Paul C. Brunson, Labbett was meant to dispense dating dos amid agency antics—counseling contestants through cringe dates and debrief disasters. But the overrun? A recipe for rage: “None expected it to go so long,” the insider dished, with Labbett’s frustration festering from a first yellow for dissent (punching a prop in petulance) to a full fury when the clock mocked mercy. “He’s not one to hide feelings—stormed out, leaving the set in stunned silence,” they added, echoing his 2022 Chase walk-off (punching a wall post-loss, blaming “shot mental health”) and 2020 red-faced rage (fuming after a £60k defeat). Celebs Go Dating’s vibe? Vanished: Katona’s comeback quest and Olivia Hawkins’ Love Island glow dimmed by the drama, while Tom Read Wilson, the receptionist rock, reportedly quipped, “The Beast’s unleashed—pass the popcorn.”

Labbett’s lament? Later leaked via apology: “Emotions got the better of me—sorry to the team and fans. Won’t happen again.” A good night’s sleep soothed the savage, and he sauntered back refreshed, but the scar? Scorching: Producers plotted contingency chaos, fearing a full finale flop. “Really stressed—thought we’d lose him for good,” the source sighed, tying it to his health hurdles (a August hypo episode halted filming mid-take, diabetes drama demanding downtime). Fans? Fractured frenzy: #BeastBlowUp trends with 1.8 million posts, defenders dubbing it “human—Beast needs a break!” while detractors decry “diva antics—fire the tantrum thrower!” Past precedents? Piling up: His 2021 Beat the Chasers “big ego” warning from co-stars (“Calm down, Mark!”), and that 2020 wall-whack that sparked Ofcom outrage (“Disgraceful!”).

This isn’t a blip; it’s a beast awakening in a genre gasping for glamour. Celebs Go Dating, E4’s guilty-pleasure goldmine (series 15 averaged 800k viewers), thrives on tension—but Labbett’s lunge? A line crossed. As Katona quips on her podcast, “Mark’s a mate, but my word, what a walk-out!” insiders eye edits: Will the strop make the cut, or get snipped like his temper? Slot’s no stranger to spotlight stress—post-divorce from Katie Thurston in 2022, he’s hunted love on First Dates flops—but this? A career curveball. “He’d had enough—of the overrun, the optics, the ‘expert’ egg on his face,” the source surmised. Crew? Stunned into silence, then sympathy: “We get it—11 hours is hell.” Fans flood Insta: “Beast mode: Off-set edition!” vs. “Unprofessional—Chase him out!”

Labbett’s “beastly” behaviour? A beastly reminder: Even quiz kings crack under camera crush. As series 15 sizzles toward screens (autumn drop), one truth thunders: Chaos sells, but walk-outs wound. Mark’s mended his mess—for now. But the door? Ajar for more drama. Anfield awaits—no, wait, that’s Slot. For Labbett? Love’s labyrinth, laced with lunacy. Tune in; the Beast’s back—but beware the bite.
