Cobra Kai's Tanner Buchanan and Mary Mouser took everyone by surprised when they only confirmed their relationship and engagement after part three of the Netflix hit was released.

Tori Nichols and Eli Moskowitz stars Peyton List and Jacob Bertrand had known one another before making their way onto the Cobra Kai set. They played brother and sister Ellie and Jack in the 2016 Disney film The Swap where the pair swapped bodies ahead of their individual major sporting competitions.

The actor added that the entire cast kept the newly engaged couple's romantic relationship a secret for "a couple years"
