Dappy and Jim Davidson are the remaining two housemates in the final tonight (January 29).
Locke summed up his time in the house, saying: "I literally have had the most bizarre experience of my entire life."
He also spoke about the row that happened in the house when he was nominated: "I thought if I was going to stick up for myself at any point then that was the right time.
"You have to love yourself a little bit sometimes."
The Made in Chelsea star also addressed his potential romance with Sam Faiers, referring to her as "my beautiful Sam".
He said: "I adore Sam. I like her a lot more than a friend. We haven't really spoken about it.
"I very much want to take her out for dinner. I want to take her on a Southbank walk in London."
When asked if they have a future together, he added: "Who knows? As reality TV has taught me, you have absolutely no idea what's going to happen."
