Jemma Lucy has branded Sarah Harding a "d**k tease."

The 'Celebrity Big Brother' contestant has lashed out at the former Girls Aloud singer, whom she's clashed with numerous times since they entered the abode, after she shared a smooch with Chad Johnson in front of the cameras over the weekend.

Speaking in the diary room about the pair's lip-locking session, Jemma said: "She is an absolute d**k tease. She doesn't even like him!"

And she's not the only housemate who is worried about Sarah's motives as Brandi Glanville has warned the hunk that he'll end up getting his heart broken.

She told him: "She gets the sexiest guy. You get a broken heart."

Chad's doubts came after the 35-year-old singer told him that they need to "tone down" their romance following their steamy kiss because she has a boyfriend, who she has been dating for four weeks, on the outside and wants to spare his feelings.

She said: "We got busted big time. We care about each other and we're best friends in the house, but I just want to draw a line under it. I just feel terrible that I let my emotions get the better of me... I don't want to make a fool out of anybody.

"You're single and I've only been dating for four weeks, but I don't want to hurt someone who is a good person - they don't deserve to be hurt. I need to respect other people on the outside and take responsibility for my actions."

Speaking about their kiss in the diary room later on, Chad said: "You can tell she's pulled back and I have to do the same. I'm not happy about it. She says we got caught up in the emotions, but I didn't get caught up, I knew I liked her."
