Big Brother returns for its 21st season with a two-night premiere event on Tuesday, June 25, and Wednesday, June 26.

That means another season of huge twists, big fights, breathtaking blindsides, and Julie Chen Moonves saying those magic words: "Expect the unexpected."

Are you ready to watch every Big Brother episode and the live feeds when it all kicks off this summer? Are you sure? Because if you're a cord-cutter, you not only need to know how to watch Big Brother online, but also how to watch Big Brother live.

If you're a Big Brother superfan who wants — no, needs! — to stream the upcoming season (as well as past ones) then you're in the right place. Here's how to watch Big Brother online...

Watch Big Brother on CBS All Access

CBS All Access subscribers can stream Big Brother 21 episodes live. That's right. LIVE! And that's not all: They can also watch every single episode of Big Brother, from Season 1 to the latest entries, whenever they want.

All Access members also have the ability to stream the live feeds, so they won't miss a single second of drama or tomfoolery inside the house.

CBS All Access does offer a free one-week trial. After that, it's $5.99 per month for the limited commercials subscription, while the commercial-free version is $9.99 per month. You can sign up here.

Stream Big Brother on Amazon Prime Video

Non-All Access subscribers can stream Seasons 13 through 20 of Big Brother with the Amazon Prime Video service.

The cost per episode ranges from $1.99 to $2.99, while entire seasons are listed between $9.99 and $19.99. You can sign up here.

Watch Big Brother on an Alternate Subscription Streaming Service

CBS is also available on other subscription streaming services, such as DirecTVNow, YouTube TV, Hulu with Live TV, and PlayStation Vue.

The prices for these services vary, depending on the selected package.

Unlike CBS All Access, past seasons of Big Brother are unavailable to stream.

Now you can enjoy every episode of the incredibly popular CBS reality show before the 21st season starts.
