The MIC stars joined forces to take part in a special E4 takeover, which saw them answering questions from fans on the show's official website.
One follower asked the pair which cast member they would most like to be for a day. Stephanie was quick to reply, saying: "Mark Francis, as then I could speak Italian all day!"
It didn't take Jamie long to think of an answer either, and he opted for his ex-fling Lucy Watson.
Proving that she is well and truly on the ball, Stephanie pointed out that Jamie had chosen Lucy so he could wear her underwear all day.
After bursting into laughter, Jamie admitted that she was correct!
US star Stephanie dramatically returned to Made In Chelsea this week by turning up at Rosie Fortescue's ball.
Stunning her ex-boyfriend Spencer Matthews, Stephanie stalked into the room and declared: "Hey a**hole! You're such a piece of s***." Woah!
Meanwhile, while Stephanie has spent the day with his boi Jamie, Spencer has been trying out a new hairstyle with Binky Felstead.
