We can all identify with waking up on a Sunday morning with a bit of a fuzzy head.

After a few drinks on a Saturday night, many of us will wake up on a Sunday with a banging headache, perhaps sweating uncontrollably and hankering for a garlic cheese chips. What's the harm? We're all only human. One person who is accused of being hungover or even still drunk on live television is our very own Brian McFadden. Spotted on Metro, Brian appeared with Keith Duffy to promote the men's upcoming Boyzlife tour but what really caught viewer's attentions was the behaviour of Brian while on the show. Hosts Tim Lovejoy and Simon Rimmer interviewed the two Irishmen about the tour and asked Keith how she came up with idea. Keith was stuck for the words to describe how he based the idea on his own life when Brian interrupted to say:

"An autobiographical show Keith is the word you’re looking for. "I told you we’re anorexic."

The joke (where Brian meant to say dyslexic) left the hosts and Keith looking visibly awkward, and viewers at home did not miss a beat, tweeting about the strange behaviour of Brian.

come on @BrianMcFadden what's in that mug?? ?????????#sundaybrunch

Bit of an awkward interview. Tim is having none of it and Brian sounds like he's on the sauce. #SundayBrunch

Give Brian a slap ...he is not remotely amusing with his anorexic 'joke' #sundaybrunch

Did Brian McFadden really just use anorexia as part of a joke?? Absolute knobhead @SundayBrunchC4 #SundayBrunch

Could it be due to the timing of Channel 4's Sunday Brunch that celebrities act strangely? Little Mix were previously thought to be drunk while on the cookery show also... So relax Brian, you're not alone!
