Ollie and Dappy became firm friends following their stint on Celebrity Big Brother earlier this year and they seemed pretty excited to be back together again.
Taking to Twitter on Sunday (21 September), Ollie said: "I have never been so excited about filming this week.. Me and @TheDappy are off on an adventure?? Shhhh @ITV Xx."
Ooh, we're intrigued!
Posing for another selfie, former Made In Chelsea star Ollie said: "Filming with one of my bizzles @TheDappy x."
Although they were busy filming, we wonder if they reminisced about their time in the house?
N-Dubz rapper Dappy struck up a close bond with Ollie and the pair often enjoyed impersonating one another. Reality star Ollie even got a Dappy makeover - and the results were hilarious!
Even after their stint in the house, the pair talked about going shopping together and Ollie even invited Dappy down to Chelsea for a night out!
