I'm A Celeb duo, Ant and Dec, have recently revealed what surprised them the most and recalled Cara Delevingne’s request.

While candidly conversing on their show, Hanging Out with Ant and Dec podcast, the stars revealed an incident that they were “unsure” of.

The pair revealed that they were surprised when recently they were reached out by the supermodel for a unexpected request.

They continued that Cara slid into their DMs as she requested them to record a birthday wish for the superstar, Margot Robbie.

Calling it a “wind up”, Dec stated, “'We had to record a birthday message for Margot Robbie.”

He added, “We got a message from Cara Delevingne on Instagram saying, "I'm going to Margot Robbie's birthday, can you record her a message because she loves you guys.”

The stars also admitted that at first, they thought someone was pranking them, and they were not able to believe that the Barbie star was their “super fan.”

Dec concluded as he revealed that he received reassurance from the Only Murders in the Building actress, “Yeah we did, like A. was this really Cara Delevingne, B. is she talking really about Margot Robbie and is she really a fan.”

Notably, both extended their wishes to Margot later.
