Julie Chen Moonves goes missing in Big Brother 27 premiere: Mysterious twist shocks houseguests

Julie Chen Moonves has been the host of Big Brother for 25 years straight. No matter the cast or twist, Julie has always welcomed viewers at the start of the show. But this time, something weird happens in the season premiere of Big Brother 27, as per the reports.

The premiere is a 90-minute episode airing on July 10, 2025, at 8:00 PM ET/PT on CBS. In the sneak peek clip released by CBS, Julie starts her usual intro for the 16 new houseguests. A loud clock ticking plays in the background, giving creepy vibes, according to the report by Parade.

Suddenly, lights go off and things get strange

Right before Julie can say her iconic line “expect the unexpected”, the lights suddenly go out. The houseguests are left in total darkness and seem confused. After a few seconds, they try to get up and look for a way to turn the lights back on, according to the reports.

There’s a hidden panel with a keyhole that flips open on a desk – but no one notices it. This could be one of the many secrets in the new theme, “Hotel Mystere.” When the lights finally come back, a houseguest named Mickey Lee yells, “Julie’s gone!” , according to the report by Parade.

Julie disappears and mystery begins

A wide shot of the studio confirms it: Julie is missing from the stage. The background screens now say: “MISSING HOST.” The only clue left behind is one of Julie’s shoes on the stage. It’s not a fairytale moment – it’s the start of a big mystery twist in Big Brother 27, as stated by the reports.

According to the report by Parade, this season is teased as a “Summer of Mystery.” The first big mystery, where is Julie? Another mystery: Is Julie’s disappearance connected to the "Mystery Houseguest" who will join as the 17th player?
