Arriving over the weekend, Cooke was delighted to receive an early card from family - except upon opening the card, Rob was greeted with a hilariously amusing 'typo'.
The message, alongside the card's inset festive greeting, read: 'Rob, have a fun one and try not to work too hard, love Leslie and Rory.'
One word caught the cheeky eye of Rob, as well as several other Twitter users.
Hilarious!
