Big Brother Australia’s Josh and Tay were caught on camera sharing a steamy kiss just hours after entering the house

Big Brother Australia returned to TV screens on Monday night.

And the new season is already heating up, with two housemates caught sharing a steamy kiss on camera during the show’s premiere.

Josh, 28, and Tay, 20, passionately cuddled just one day after entering the house and admitting they were attracted to each other.

“Myself and Tay? One hundred percent,” Jay told Big Brother.

Tay also said she was excited by Josh’s confession, adding, “I was happy because I think Josh is definitely the one – out of everyone in the house, 100 percent for sure.”

The next day, the housemates were asked to select two people to enter the ‘King and Queen Suite’.

The Big Brother contestants nominated Josh and Tay to spend the first night in the suite, which features a large bed and luxurious bath.

“It’s a privilege to be the first king of the house and I couldn’t ask for a better queen,” Josh said.

“I only met her yesterday, but Tay… she’s an incredible girl and looks amazing too, very beautiful.”

After entering the room, Tay and Josh were seen cuddling in bed before Big Brother dimmed the lights.

They then shared a steamy kiss, which was captured on the night vision camera.

Queensland-based Tay entered the house with her twin sister Ari Wilcoxson and they will also compete as one.
