One housemate has won immunity from this week's eviction in tonight's Big Brother 2018 highlights.
It follows new housemates Hussain Ahmed and Isabella Farnese joining Big Brother in the latest live show.
They made their entrance in Friday's episode, following the latest eviction which saw Isaac Jagroop eliminated.
As newbies, Hussain and Isabella are immune from this week's eviction.
And in a new twist, this evening Big Brother gave one of the original housemates the chance to also achieve immunity.
Big Brother's weekly auction saw housemates able to bid for immunity using their Big Coins.
"Today Big Brother is offering an extremely exclusive top lot, Immunity," Big Brother said. "Whoever wins this lot will be immune from this week's nominations and therefore the next eviction. 50 Big Coins and quickly rose."
Ahead of the auction, Tomasz Wania was the richest housemate after Isaac donated his Big Coin total to him following the eviction.
Tomasz, Sian and Lewis all bid on the lot and it was Tomasz who won it with a big of 300 Big Coins. He is therefore immune from this week's eviction.
Other lots up for grabs in the auction were cocktail making and a luxury hamper.
Meanwhile another twist has been revealed involving the new housemates.
With the pair's Big Coin totals currently at 0, the original housemates have been told they have the power to award one of the two a starting Big Coin bonus.
Unknown to Hussain and Isabella, the original housemates will hold a vote on Monday to determine who will get the Big Coins.
The original housemates cannot disclose and reveal the upcoming vote to the new housemates.
The latest round of nominations were held on Sunday night and the results will be revealed in Monday night's highlights show.
Big Brother 2018 continues Sunday-Friday nights at 10PM on Channel 5.
