While preparing for her 'Endless Love' duet with Nick, the Gladiators host announced that she believed Brian was certain to make it to the final three along with Nadia and Victor.
"[Victor's] so nice and funny," Ulrika continued.
"He said it would be very cool for him 'cos he's never made the final week," Brian said.
However, Ulrika couldn't bring herself to agree with Brian's suggestion that Nikki could also be a contender for the title, arguing that she wasn't sure if the BB7 drama queen had a big enough fan base in the outside world.
The pair's thoughts then turned to this week's eviction, with Brian saying: "Friday could be an interesting one for everyone, there could be a few shocks."
The Irish housemate proceeded to dispute Ulrika's claims that she would fall victim to the public vote this week.
"If I was watching it as a viewer I wouldn't vote to get you out. You don’t offend me that much, you don't wind me up that much," he said. "It could be a shock and it could be the people we least expect."
Speculating that Big Brother would unleash some form of twist on Friday, Ulrika suggested: "[The evictees] could be going into another house. That's when I'll need an intravenous drip of morphine or something."
Brian is currently the hot favourite to become the Ultimate Big Brother housemate, while Makosi and Nadia are expected to be axed in this week's double eviction.
