Casey and Ollie, who starred in the most recent series of CBB, arrived on the coast yesterday afternoon (3 April) after heading south west with a group of friends.
During the trip down from London, Casey filmed a funny Instagram video of herself and Ollie singing along to the Lighthouse Family in the car.
Alongside it, she commented: "Road trip!!!!!! @planetolliewood." (Watch it below!)
After arriving, Casey posted a photograph of herself on Instagram, and it shows her standing in front of a gorgeous beach with her arms outstretched.
She told her followers: "We've arrived :) Hello Cornwall. Going to be a lovely little weekend. Xx."
Later, the gang headed to the local pub and showed off their gymnastic skills by climbing into a human pyramid. Ollie bravely opted for the bottom row, while Casey knelt on his back.
Sharing another photo, Casey added: "The pyramid in Cornwall!! #pub #cornwall #pyramid #pub."
Have a great time, guys. And next time, please invite us!
