The Jersey Shore star and Kemp gave Danica the nickname because of her ability to "hook" men with her flirting.
Danica was criticised for being overly affectionate with The Situation and Prince Lorenzo in the house when she currently has a boyfriend outside of the show.
Speaking about his relationship with the lingerie model, the US TV personality said: "She definitely was special.
"However, me and Martin were talking about this last night, and he said she was the best fisherwoman he's ever seen, she'd reel you in then go get her next fish."
Kemp commented: "At times she could see it was hurting you, but she still wouldn't leave you alone. I bet she's got her hook and reel out tomorrow."
The Situation replied: "I bet she's chilling with Princey today but as soon as finals come, Prince is to the side and she's coming with her f**king hook."
Celebrity Big Brother concludes on Friday (September 7) on Channel 5.
