Alfie Deyes, Zoe's bae, made the connection after watching the popular baking show. Tweeting this comparison to fans has caused a meltdown on Twitter:
But Alfie wasn't the only one to notice the doppleganger! Fans of the YouTube star took to Twitter to express their surprise at the similarities between Zoe and Candice...
