Just in case, I have included a link below to watch the Big Brother Live Episode tonight since my area will be airing an Exhibition Football Game during the time of Big Brother and will not be airing the episode until 3AM.
Anyway, I hope this helps. You may want to bookmark this link in case the Republican or Democratic Conventions affect the airing of additional BB episodes later on this season.

Enjoy the show!
