League legend Andrew Johns has apologised to a woman who accused him of "disgusting, disgraceful" behaviour while heavily drunk at an airport in Queensland.

Johns was photographed lying on the floor at Toowoomba's Wellcamp airport on Friday night after allegedly propositioning the married woman, who labelled Johns' behaviour "a very bad example".

"Andrew Johns was absolutely disgraceful," Helen Wright posted in a Facebook message to Channel Nine's Today Show on Saturday morning.

"He was severely intoxicated. I am a 42 year old woman that he asked to kiss him. When I refused to kiss him and replied I was happily married and had three sons, his question to me was 'did you have a cesarean birth?'
