Fans will tonight see Saira branding Bear "vile" in the Diary Room, before Renee Graziano tells Bear that he should back off from the Loose Women presenter.
Speaking to the Ex On The Beach star in private, Mob Wives' Renee warns him to "leave it alone" with Saira.
Saira has noticed Bear confiding in Renee in recent days and is unimpressed. She tells Big Brother: "He's so vile! Renee has a soft spot for him, he now has a defender for all his actions and behaviour."
Earlier in the show, she calls him a "d*ckhead" to his face after he discovers she nominated Grant Bovey for eviction.
However, in a move that may surprise fans - especially given all of the above - the pair attempt to reconcile their differences later in tonight's episode.
In the kitchen, Saira apologises to Bear for calling him the name, adding: "I'm a mature woman and I should control myself." They then hug. Yes, HUG!
Tension between Saira and Bear began to mount from Day 1 in the house following a dispute over wardrobe space.
Since then, the pair have had several major confrontations, not helped by Bear 'daring' Marnie Simpson to expose her breasts in Saira's face following a row.
Celebrity Big Brother continues tonight at 9pm on Channel 5.
