Big Brother Season 21, Episode 1 live stream: How to watch

As Big Brother kicks off its new season on CBS, here’s everything you need to know about the Season 21 premiere including details on how and when to watch!

Summer has officially begun and with it comes the return of CBS’ hit summer staple (and our favorite guilty pleasure), Big Brother! Although we once again had a celebrity season to help whet our appetite during the hiatus season, there’s nothing quite like CBS’ annual summer season and CBS is looking to once again serve up a memorable summer!

Keeping with tradition, Season 21 is set to kick off with a special 2-night premiere event kicking off this Tuesday night as 16 new Houseguests move into the Big Brother house to compete for the   $500,000 grand prize.

While the exact events of Tuesday’s premiere remain unclear, it seems like CBS will keep with tradition of using the first hours of the season to introduce users to the season’s Houseguests (or at least half of them), share some teasers about the season’s twists and kickstart the season with the summer’s first Head of Household competition! In other words, fasten your seatbelt because we’re in for quite the ride.
