The polo player said his eviction was a 'mutual' decision between him and leading lady Sophie Monk.
'I think that Sophie and I had just realised we weren't for each other,' he said in an interview with Popsugar. 'It was sort of a mutual thing.'
He added: 'We both enjoyed each others' company quite a lot as mates, but there wasn't that spark.'
Wednesday night's episode saw Sophie eliminate three contestants, including Pete, Jefferson and Eden.
Next week, four intruders are expected to enter the house.
