The upcoming instalment of the spin-off, which premiered earlier this month, will see the comedian take part in Cut Throat Cliff alongside Beverley Callard, Sinitta and Mo Farrah.
The pair, who are both taking part in the current series of I'm A Celebrity... South Africa, have not seen eye to eye since coming together in the Main Camp.
Sinitta opened up about her relationship with ex Simon Cowell on Friday's I'm A Celebrity All Stars, as she candidly shared the reason why their relationship failed.
The former TOWIE star, 45, took to her Instagram to make a snide remark at the 62-year-old after a pretty awkward moment between the pair that aired on the ITV show on Thursday night.
The singer furiously accused ITV of editing the clash between the pair, which took place during Thursday night's episode of the All Stars series of the show.
