Big Brother is back in July and is promising the biggest season ever with supersized episodes and a new spin-off.

The new season kicks off with a 90-minute premiere Thursday, July 10 (8:00-9:30 PM, ET/PT) followed by a 90-minute Sunday episode July 13 (8:00-9:30 PM, ET/PT).

After its premiere, the series will air Wednesdays (8:00-9:30 PM, ET/delayed PT) expanded from its regular 60-minute episodes, followed by hour-long shows on Thursdays – featuring live evictions – and Sundays (8:00-9:00 PM, ET/delayed PT).

New this year will be Big Brother: Unlocked on Friday nights throughout the season. Three BB All-Stars offer never-before-seen broadcast footage from the house, exclusive interviews, surprise guest appearances and unprecedented behind-the-scenes access. They will also share first-hand insight and expertise as they analyze gameplay, assess the competition and give their insider’s perspective every other Friday starting Friday, July 25 (8:00-9:00 PM, ET/PT).

Paramount+ subscribers and Pluto TV viewers can continue to catch all the action on the Big Brother Live Feeds.
