Kav told his Twitter followers last night (9 February) that the pair are set to release a new track titled 'De Ja Vu' very soon.
He tweeted: "For the lovely people asking, yes I have song landing soon 'De ja vu' with @AlexanderO_Neal #letsdance."
Kav and 80s soul singer Alexander spoke about collaborating during their time in the house, so it's no surprise to see their plans in action.
In fact, 'Criticise' hitmaker Alexander told Reveal last month: "We have spoken about doing some projects together and I definitely look forward to working with Kav. I have a lot of respect for him and a lot of love, and the man is talented too. I don't work with people who are not talented."
Kav, who came seventh place in CBB's grand finale last week, is known for his 90s single 'I Can Make You Feel Good'.
The 37-year-old also took part in the second series of The Big Reunion last year, where he joined Dane Bowers, Adam Rickitt, Gareth Gates and Kenzie to form new supergroup, 5th Story.
Elsewhere, Alexander has also teased a potential duet with CBB winner Katie Price, despite admitting "he's never heard her sing a note".
And two weeks ago, Alexander sparked speculation that he was recording a song with X Factor star Jay James Picton.
