With the Ex On The Beach star facing eviction tonight, his brother appeared on Bit On The Side to drum up votes for his prankster brother, who is this summer's most divisive character.
"I wouldn't say he's a nuisance," said Robert, appearing in Rylan's Professor Clark-Neal's classroom segment.
"He's more like an entertainer. It's a giant playground and Steve's head boy, just having the time of his life. Vote for Steve. He is a born entertainer. At least someone is making the other celebs work for a change."
Bear, who is eternally nominated thanks to the housemates' earlier decision, is up against his house girlfriend Chloe Khan, Marnie Simpson and James Whale, and one of them will be going home on Friday night.
Also on CBBBOTS was former Big Brother housemate Harry Amelia, who is good friends with Chloe. She admitted she reckons Bear is overshadowing Chloe in the house: "I'm not one to tell her who she can be friends with but I think it's time we saw Chloe's personality rather than Bear's. Chloe is just a normal girl like me or you."
Chloe was a late addition to the nominee's table after being put up by Renee Graziano last night. Renee was initially nominated herself, thanks to Bear's killer nomination, but won the right to out someone else up in her place as part of a task.
She chose Chloe who was none too happy, lashing out at Renee: "You try to put your authority down by making people scared of you," replied Chloe. "You have a lot of insecurities and as long as you have girls in your ass, licking your ass, you feel fine. But when they step away, you hate it."
CBB continues 9pm on Channel 5.
