N-Dubz star Dappy complains to The Apprentice star that she "violated" him.
“You cannot be scared to speak out," she replies.
Dappy tells her: “But you speak out too quick, you point the finger and you are fiery, you point out and why do you just hold that back.”
Luisa explains “Because that’s not me, you are who you are and I am who I am.
"I’m cool, I’ve held myself back and that’s fine hold yourself back if you want to get the public to like you because you’re so scared of speaking out, I’m not saying it that to be mean. It’s like you don’t sit with us you don’t speak with us and for us when we like you, I care about you, and it’s like what’s up.
"When I say you’ve been sleeping all day I didn’t mean it like it like you’ve taking it”.
Dappy says: “It’s like someone punching me in my face, that’s how it felt.”
“Well then I apologise," Luisa adds.
“Appreciate it," concludes Dappy.
See just why it all kicked off between the pair when Celebrity Big Brother 2014 airs tonight at 9PM on Channel 5.
