Hailey and Justin Bieber are continuing to beef with TikToker Julie Theis … slapping her with a cease-and-desist letter that claims she fabricated her story about their celebrity marriage.

TMZ obtained a copy of the letter written by the Biebers’ attorney Evan Spiegel … who writes that Theis posted “outrageous false, fabricated, and defamatory” statements online about the couple’s marriage.

Spiegel also writes Theis uploaded TikTok and Instagram videos of herself claiming that Justin and Hailey’s marriage was a great example of an abusive relationship stemming from drug addiction, and calls the allegations “highly damaging.”

Theis added … “It’s extremely elitist to try to silence opinions just because you disagree. Disagreement is not defamation.” She also claims she’s been receiving death threats since the start of this drama.

Cincinnati Bengals cornerback Cam Taylor-Britt is lucky to be alive — the NFL-er told police he was a passenger in a terrifying crash in November, when a vehicle flipped in the street after colliding with a parked car.

The moment was caught on surveillance footage, which showed a black Jeep — registered to Taylor-Britt — blowing through a red light around 3 AM on November 15.

The car rolled over and onto its roof … and out of frame.

When speaking with cops, Taylor-Britt acknowledged his license was suspended at the time.

Ultimately, Booker stated he was the driver … after initially blaming it on a drunk “female” who ran off after the crash.

This incident happened the day before Taylor-Britt suffered a season-ending injury during the Bengals vs. Steelers game.

Brian Austin Green‘s getting real about a blast from his dating past … opening up about his time seeing Tichina Arnold and revealing she was adamant their hookups stay strictly under wraps!

Speaking on Deon Cole‘s “Funny Knowing You” podcast, Brian said keeping the romance a secret triggered deep insecurities, especially since he already felt like he didn’t fully fit into or feel accepted by the culture around him at the time.

Brian said it really sucked feeling like the person he was into didn’t even want her pals knowing they were together … and, while she eventually became more open about it, he realized the relationship wasn’t healthy, especially since it didn’t even start from an honest place to begin with.
