If there's one thing that any Oasis fan - nay, any music fan with a passing knowledge of British rock - knows, it's that Noel Gallagher and Liam Gallagher are two very different people. Confuse them at your peril.
Unfortunately, it seems that Mo Farah didn't get that memo as he did just that yesterday when he posted a picture to Instagram of himself with Noel, who has been supporting U2, at their Twickenham gig.
He captioned the Twitter link to the post: "Chilling with my boy liamgallagher U2 concert at Twickenham..!!" - but the only problem is... it was a picture with Noel.
However, Liam saved the day by having the most Liam response to the situation ever:

You've gotta love 'im.
The offending picture - which he went back to tag correctly with Noel's account on Instagram - can be seen below:
