The Block stars give fans a look at their surprising celebrity ‘transformation’ after $1.65m win on renovation show

They shot to fame as the winners of Channel's Nine renovation hit The Block this year.

And now Steph and Gian Ottavio, both 27, have treated fans to a glimpse into their new celebrity lifestyle.

Posting to Instagram on Wednesday, Gian revealed that the couple treated themselves to a teeth whitening treatment.

Gian posted a photo gallery on his Instagram Stories showing off the procedure.

Their Block co-star Eliza Paschke also joined the couple for the treatment.

One photo shows The Block's favorites lying on a couch with LED lights over their mouths.

“A rare moment of silence in the house,” Gian joked on his post.

Meanwhile, Eliza's sister, Liberty, who also starred on The Block this season, criticized her sibling writing in the comment sections of Gian's post:

“Literally the only thing that will ever shut Eliza up.”

The treatment lasted three 20-minute treatments and was carried out by Blanc Smile Sydney, a teeth whitening specialist, at Gian and Steph's home.

Owner Natasha Ianni shared Yahoo that Steph and Gian's teeth are now 'eight shades lighter' after the treatment removed coffee, tea and other stains from their grinders.

Steph and Gian Ottavio took home the Block Australia crown in November when they sold their Hampton East home for $5 million and made $1.75 million in profit.
