Alex Lahey Absolutely Crushed Her Debut US Late Night Appearance

Alex Lahey has taken full advantage of her debut US late night TV appearance by crushing her performance on Late Night With Seth Meyers.

If there were any pre-show jitters you wouldn't have even known as the Melbourne artist flawlessly belted out her single, Every Day's The Weekend.

As an extra special nod back to Australia, Lahey's drummer had the 'YES' tag featured on his kit, acknowledging the result of this week's marriage equality vote. 

Check out the performance below.
