She explained that spitting in Bear's food had been intended as a joke and apologised.

Bear appeared unfazed by the incident, telling Big Brother: "Big deal! I'll probably put her up for nomination every single week. I've had worse in my mouth!"

Apologising, O'Day told Bear: "I'm sorry. It was not done in a malicious way."

He gave her a hug, saying: "If you want to kiss me that bad you can."
