The N-Dubz songstress cheered Dappy on, as he was announced runner-up on the evening (29 January) and was spotted standing in the rain and the cold, waiting for her cousin to make his exit.
Once she and her older cousin had been reunited, Tulisa then got to know flirtatious former housemate Luisa and cuddled up the CBB presenter Emma - all the while with Dappy by her side.
Clearly the two pop stars were eager to celebrate Dappy coming second to Jim Davidson and returning to the normal world, as they appeared to be in good spirits at the after party.
One of the snaps from their celebrations shows Tulisa planting a big kiss on the chart-topping rapper and looking elated to have him back.
She added the caption: "Here he is my lil duk daps x"
Last week Tulisa admitted that she couldn't wait to give Dappy a cuddle, so we can imagine she is showering him with as many hugs and kisses as she can now that he's out of the CBB house.
The 25-year-old singer was also joined at the Elstree Studios in Hertfordshire by ex-TOWIE regular Kirk Norcross, who went along to support Dappy too, since the pair have built a close friendship over the last year.
Kirk tweeted yesterday: "So much respect for @TheDappy love you my brother #CBBFinal"
We wonder whether he caught up with former Essex co-star Sam Faiers while he was there?!
Rylan Clark, host of Big Brother's Bit On The Side, was seen at the afterparty with the gang as well and couldn't resist posing for a fun Instagram photo too.
