They are the most recognisable contestants on this season of The Block.

But Kylie and Brad Baker looked very different during the finale of the show on Sunday night.

After storming off the set last week and insisting she would not be present on auction day, Kylie made a shock return alongside Brad.

The hairdresser revealed a fresh set of blonde hair extensions after ditching her fluorescent green locks, while Brad sported a very manicured moustache.

The fiery reality star also opted for a daring outfit for auction day, showing off her ample cleavage in a low-cut green metallic dress.

She accessorised with large gold cross earrings and wore a heavy application of glamorous makeup.

Meanwhile, Brad revealed his fresh dark tan in an unbutton pattern shirt and opted to go without the glasses he has been wearing all season.

Later, Kylie changed into a sheer yellow dress that showed off her cleavage and a huge rose tattoo on her sternum.

The controversial couple sensationally returned to the series on Sunday night in time for auction day after the mother-of-four vowed she would never return to the Channel Nine show last week.

In another shock move, the teams also opted to keep details of their home’s reserve price confidential from other competitors.

In recent weeks, Kylie and husband Brad saw their seven-year marriage implode on-air after the Cairns-based tradesman told fellow contestant Mimi Belperio he would ‘follow’ her OnlyFans account if she had one.

In a dramatic lead-up to the final round of judging last week, tensions reached boiling point when Kylie ordered her team to stop work just hours before the last reveal and abruptly left.

The couple’s return on Sunday night sparked fierce reactions from fans, with many questioning why they were allowed back on the set.

On X, formally known as Twitter, fans voiced their concerns over Kylie and Brad’s continued involvement in the show.

‘Kylie and Brad should be disqualified and the profits shared between the tradies,’ one user exclaimed.

Another user said: ‘Being allowed to return just diminished the behavioural standards for future contestants.

‘That behaviour should have been used as an example that it will not be accepted.’

‘The Block really is turning into MAFS it seems,’ they added.

‘So Kylie and Brad have come crawling back obviously for the possible $,’ wrote another viewer.

‘They should not be allowed to win anything, what the [expletive],’ quipped another.

‘The producer’s really are milking it,’ wrote one more, before adding: ‘Fark Kylie and Brad back again’.

Kylie unleashed a foul-mouthed tirade on the show last Sunday and ordered her tradies off-site.

With her dramatic exit, Kylie sealed her promise to boycott auction day, even if it meant forfeiting any potential profits from her time on The Block.

Kylie split from her husband Brad on national TV during last week, following his flirtatious comments to Mimi Belperio. They are now back together after working on their marriage.

The couple, who share four children together, saw their relationship implode when plumber Brad, 32, told Mimi he would ‘follow’ her OnlyFans account if she had one.
