The Block fan favourite is unrecognisable in topless photo from past career

The Block star Sarah-Jane Wilson has exposed her husband Tom Calleja as a former ‘party bus host’ who regularly herds teens around nightclubs with his shirt off.

She posted a photo of a young Tom, who bore a striking resemblance to Shannon Noll during his Australian Idol days, shirtless in a pair of low-rise jeans with his Bonds underpants sticking out of the top.

“If a follower finds a picture of Tom flipping through her old albums – around the host of a party bus,” the mother of one wrote.

“To me, it’s the Bonds jocks in the low-rise jeans.”

Several followers noted that Tom, now 34, was a death ringer for a young Shannon Noll, with one writing, “I thought Shannon Noll was singing about a big black shiny car, not a bus.”

Had to look twice to see who was tagged. Thought it was Nollsy,” wrote another.

“At first glance I thought this was Shannon Noll,” said a third.

Tom and Sarah-Jane, 30, were one of the more popular teams on The Block last year.

They were known for their strong work ethic, but also for their blazing rows.

During the finals, their renovated home in the Macedon Ranges was auctioned with $4.08 million in reserve, but sold for only $4.1 million.

This meant they walked away with a measly $20,000 for their efforts.

The couple was forced to sell their car to make up for the shortfall.
