Dappy just missed out on winning CBB to Jim Davidson, yet Tulisa couldn't be more proud of him and was waiting outside the house last night.
The former X Factor judge cheered and clapped as Dappy - real name Costadinos Contostavlos - made his exit into the real world, and she hugged him once he'd finished his interview with Emma Willis.
Spotting her in the audience at Elstree Studios in Hertfordshire, Dappy's face lit up as he squealed: "Tulisa!"
Tulisa, who shot to fame in N-Dubz with Dappy and their pal Fazer, has now spoken out and thanked viewers for picking up the phone and voting for her cousin.
Taking to Twitter, she said: "Yaaaaaay thanks u guys, we love u so much. Thanks 4 the support, he did so well, thanks 2 u guys, nuff love n thank u ndubletts n Dappy fans."
Earlier, she had tweeted: "Come on ndubletts and Dappy fans this is our last chance VOTE xxx."
Last night's final of the C5 show was an emotional one and showed Dappy comparing Jim to his late father Byron.
Casey Batchelor was first to leave, followed by Sam Faiers, Luisa Zissman, Ollie Locke, Dappy and then Jim.
Meanwhile, during her exit interview, Sam spoke about how ill she had been in the house, adding that her health issues left her "in bed crying".
