Viewers have seen Saira and Bear clash on occasion in the house and last night she warned him he wouldn't win the show if he carried on behaving in such a divisive way.
Speaking on Bit On The Side, her pal and fellow Loose Women star Coleen said: "Saira is very opinionated – that's why she's a Loose Woman! – but she does try to see the good in everyone and she has a motherly instinct, with Bear especially.
"I think she's trying to say, 'You're being a pain in the ass but I know that there is a nice guy in there, so try to show it more.'"
Coleen, who appeared in CBB in 2012, added: "She is absolutely 100 per cent [being herself]. She is genuinely interested in everybody. She never stops talking but it's all really genuine. She's really caring. She's just friendly with everyone and can adapt to every situation. She has such a heart of gold, I swear. If she was a nightmare and that wasn't the real Saira, I would be the first on the phone saying, 'Get her out!'"
Saira faces Bear, Heavy D and Lewis Bloor in tonight's live eviction, which will see a second housemate evicted from the series. Grant Bovey was the first housemate to go, while Christopher Biggins was removed for making "offensive comments."
CBB airs 9pm on Channel 5.
