It's reported that Pat, 61, was speaking at the Conference News Agency Awards at the Queen Elizabeth II Conference Centre in London when he made a jibe about company boss Lizzy Eaton’s chest in front of around 400 people.
Lizzy was given a T-shirt with Pat's face on it, which saw the radio star tell her: "That’s the only way I’ll get on your t**s today."
The Sun reported that Lizzy threw the top back at the presenter and proceeded to storm out of the event in tears last week.
She later wrote on social media: "Yesterday I was publicly humiliated, in a sexual nature, by the celebrity host of an industry event, on stage in front of 400 of my colleagues and peers.
“Afterwards I was in complete shock and hadn’t really processed what happened. Today I am struggling with it — I feel sad, dirty and, frankly, violated."
She continued: "I have worked incredibly hard to earn my reputation and hopefully be an inspiration to other young women in the events industry.
"Yesterday however, I was belittled, sexualised and objectified in front of hundreds of people I respect.”
