The Heart Rate Challenge comes after the villa was left in shock by the recent re-coupling.

Bombshell Konnor Ewudzi chose to steal Grace from Joey despite the couple's strong connection.

Joey dated Grace last summer after they met on holiday in Ibiza and the couple has rekindled since starring on the show together.

But Grace mistakenly gave Konnor the impression she was interested in his advances, telling him she and Joey were not 'closed off', meaning she could still be willing to get to know other suitors.

Joey has ended up in a couple with Jess White, who remains single following the end of her flirtation with Ronnie.
