Ant McPartlin and Declan Donnelly are longtime friends and co-hosts and now it turns out that the presenting duo are also related!
The pair appeared on Monday's edition of Ant & Dec's DNA Journey.
And the end of the show, their journey came to an end in Ireland where they gasped in shock as they found out they both carry the same DNA marker S660.
This marker traces all the way back to a Viking warrior, who died aged 20 over 1000 years ago.
So, while they are very distant relations, the duo can now officially get away with calling each other cousins.
The pair branded the news 'the best thing ever'.
Hello you lovely lot. Thanks again for your feedback. Glad you enjoyed watching it as much as we did making it....now, where’s my cousin...I need sun cream on my back. Declan!!!!!! ☀️
