The actor’s jibe comes after two weeks of online feuding, which began when Katie mocked Danny’s recent engagement news.
The BBC reports that after being awarded the prize, Danny told the audience at the London Grosvenor Hotel: "I don't want to give anyone the oxygen or publicity.
"But I have to say this award is for my personality and it's my personality that gets me into trouble.”
He then used the nickname he’s invented for Katie, adding: "I'd like to dedicate it to Steptoe…Please don't make vile people famous".
On the morning of his award win, Danny locked horns with Katie on Twitter for the second time in as many weeks, following the publication of her Now! magazine column.
The actor wasn't pleased with Katie’s decision to share her thoughts on the fact his fiancée Jo had decided to forgive Danny for his previous alleged infidelities.
“Taking back a man after he’s cheated on you is like letting a grizzly bear into your bed,” Katie wrote. “It will always tear your heart to pieces in the end.
“When you take back a cheater, you accept a constant nagging doubt: where is he, who is he with and when will he come home smelling of someone else?”
Danny then hit back with a series of Twitter posts, including one that read: “Your love for publicity is almost as ugly as you @KTHopkins I knew you wore a syrup...time to put Steptoe down #filth.”
It seems Danny is off the hook for the time being though, as Katie has now turned her attention to Jeremy Clarkson.
The rent-a-gob wasted no time in sharing her views after Jeremy’s ‘Top Gear’ suspension was announced, and - surprise, surprise - she’s calling for the controversial presenter to be reinstated.
“Clarkson suspended by BBC. I don't care what he said. Clarkson all the way. #TopGear #topbloke," she tweeted, adding: "JeremyClarkson v @BBC Without him, the licence fee makes no sense whatsoever. Enough lefty lunacy. Get the man back on #topbloke #TopGear."
