“Big Brother” is back, as the long-running CBS show launched its 27th season

But what happened during the Big Brother 27 premiere episode? And did viewers learn the identity of the mystery houseguest?

Here’s everything to know from premiere night.

What happened on the ‘Big Brother’ season 27 premiere?

To open the night, Julie Chen Moonves introduced the first eight houseguests:

• Kelley Jorgensen.
• Zach Cornell.
• Ashley Hollis.
• Rylie Jeffries.
• Amy Bingham.
• Adrian Rocha.
• Lauren Domingue.
• Keanu Soto.

Zach, Amy, Adrian and Kelley were the first four to enter the house, with Zach being the very first houseguest to walk through the doors (super fans know that’s a big deal).

In the diary room, Kelley complained about Amy being too loud off the jump before cameras showed a countdown clock.

The other four then entered the house.

Julie then introduced the second eight houseguests:

• Katherine Woodman.
• Vince Panaro.
• Mickey Lee.
• Jimmy Heagerty.
• Morgan Pope.
• Isaiah “Zae” Frederich
• Cliffton “Will” Williams.
• Ava Pearl.

Mickey, Zae, Katherine and Jimmy entered the house. Jimmy quickly said he and Amy had a connection.

Julie then told the last four to go into the house. Mickey mentioned that she saw some attractive men in the house, and specifically named Rylie. Zae and Keanu also mentioned having a bro connection.

Julie ultimately came on the TV and talked to the houseguests, but the countdown clock hit 00:00 and the lights went out. Once the lights came back. Julie had disappeared from the stage and left a single high heel.

The first cheesy segment of the season then occurred: An odd man in a red mask appeared on the TV and said he was behind the disappearances of Julie and the HOH relic. Julie called the houseguests on a phone and told them that eight people would try to find her and the other eight would look for the HOH relic.

Amy, Zach, Ava, Vince, Adrian, Mickey, Lauren and Rylie competed in a competition with the end goal being to save Julie. Zach ultimately won, and Julie popped out of a door.

Who is the mystery houseguest on ‘Big Brother’?

The identity is still unknown. This story will be updated throughout the night.
