“Big Brother” returns for its 19th season June 28 on Global TV, and longtime host Julie Chen is giving ET Canada’s Matte Babel all the details on this year’s theme: temptation!

“The tree says it all,” Chen says of the decorative motif. “When the houseguests walk through those doors, they are greeted underneath an apple tree – ’cause what spells ‘temptation’ like an apple?”

The biblical Garden of Eden wasn’t the only source of inspiration; in the communal bathroom, a large, Vegas-style couch invites gossip. “Where [the houseguests] feel like they have privacy, they tend to talk more,” Chen explains, “and loose lips sink ships. People don’t learn it season after season!”

And in the “Big Brother” house, nothing says “temptation” quite like a showmance. “I think there’s going to be lots of cuddling,” Chen teases.

Of course, power is a major factor in the game, and each week’s Head Of Household will get to celebrate their power by basking in the luxury of the coveted HOH room.

“If you win Head Of Household, you want to feel like you’re living large,” Chen says. “It’s so funny – when you see people up in here for a week, they become drunk with power. You see the dark side of a lot of people.”

The excess continues in the kitchen, where houseguests will enjoy their meals with literal gold – because, as Chen reasons, “What’s more decadent than gold flatware? A little bit nicer than stainless steel, right?”

The theme of temptation extends beyond the furniture, with the introduction of a new twist: the “Den Of Temptation.” Viewers will vote for one houseguest to send into the Den, where they will be tempted with a potentially game-changing offer – but every temptation will unleash a consequence on the house.
