In a completely different change of views compared to those he gave in his exit interview on Sunday night, Lee admitted he was probably to blame for the whole love triangle.
"Last night when I came out was a completely shocked, I didn't know how to react," Lee explained. "Emotions were all over the place. I'm not heartless, didn't mean to lead her [Casey] on.
"I feel really bad because I really, really like Casey... but as a friend. It's really difficult."
The Blue singer continued: "It was my fault for not being strong enough, I hold my hands up.
"I know there's a lot of people giving me flack. If anyone was offended, I'm really sorry, I'm not a bad person... I've got a good heart. I just want to say that. I just want to say sorry if I offended anyone."
Lee concluded: "I just got stuck in a love triangle that I couldn't get out of and I'm sorry for that, I'm genuinely sorry."
Lee's exit leaves Jim Davidson, Luisa Zissman, Sam Faiers, Dappy, Ollie Locke and Casey Batchelor in the house ahead of the final.
