The N-Dubz star finished in second place in last week's CBB final, coming runner-up to comedian Jim Davidson, and since leaving the house he's been noticeably pining for his former housemates' company.
Earlier today (3 February), Dappy tweeted Sam, Ollie and Luisa letting them know that he was thinking about them and missing their presence.
He told Luisa, "I miss my bad b @TheLuluLife" and swiftly added, "I also miss my homie @SamanthaFaiers", along with a photo of himself and the TOWIE beauty taken last week.
Meanwhile, ex-Made In Chelsea star Ollie replied to Dappy's heartfelt tweet by jokng: "I miss you so much too bro.. Yer.. I'm street, I say bro! Xx"
The four celebs formed a close friendship in the CBB house last month and vowed to stay in touch once they were evicted.
Last Friday (31 January), the gang reunited at the ITV studios for an appearance on breakfast show This Morning and couldn't hide their excitement at seeing each other again.
Along with pictures of the foursome, Dappy also shared a photo of himself with Myleene Klass.
Following their exit from Celebrity Big Brother, the stars have been busy getting back into their normal routines and promoting their various new projects.
While rapper Dappy has announced plans for a new UK tour, Luisa has been preparing for her new book release and baking with her daughter Dixie.
She tweeted yesterday: "Morning! Have a great Sunday today I will be baking all day with Dixie in preparation for my book photography all next week! #funtimes."
However, Sam hasn't had an easy ride since leaving the Channel 5 show.
After falling ill with a mystery virus in the CBB house, Sam was taken to hospital on more than one occasion and she is back in hospital again this week.
Luisa made sure that she was quick to send some love to her new pal and tweeted: "Sending big love and snuggles and tickles to @SamanthaFaiers."
