While sunbathing in the garden with Makosi, the Portuguese reality star pondered whether the intensity of the Big Brother experience was turning her into a more negative person.
"I'm tired of a being a bitch," she bemoaned. "It's not who I am. Or maybe it was and I didn't realise.
"You just have observational opinions about the people in here, you don't have anything else [to do] and you become either a positive observational person or..."
"A negative one," finished Makosi.
Nadia nodded and continued: "I'm becoming observational with the things that annoy me first. I think it's my competitive streak. I'm ambitious and that can be seen not as a good thing."
Having overheard a juicy-sounding late night conversation Nadia was having last night, Makosi then pressed the BB5 winner for details of who she had been talking about, but the 35-year-old refused to dish the dirt so soon after despairing at her gossipy streak.
However, it didn't take long for Nadia to crack, as she revealed that she was beginning to tire of Brian's perceived 'performing'.
"I feel like Brian's not here to have a conversation with us, he's here to interview us," she said.
"With him it's not interviewing, it's being a part of every group in the house, but we know which group he belongs to," Makosi replied.
Nadia agreed with Makosi's assessment of Brian's tendency to float between groups, comparing him to "a puppet on a string." The pair then stated their belief that the BB2 winner was playing on his sexuality in an attempt to capture votes.
