The actor, who plays camp knicker-stitcher-turned-barman Sean Tully in the ITV1 soap, agreed the 12-month deal with just six weeks of his current contract left.
Last year we told how Antony, 32 next week, threatened to quit unless he was paid £80,000 a year.
He then signed a new contract in September. His latest deal comes after ITV bosses gave him his own 5pm chat show, starting next month.
Antony, who was named best actor at the British Soap Awards in May this year, will continue with his Corrie role as both shows are made at Manchester’s Granada Studios.
He is currently at the centre of a big Weatherfield storyline in which his gay character is having a baby with best pal Violet Wilson.
For his new afternoon programme, The Antony Cotton Show, he has even roped in his actress mum Enid Dunn to be a roving reporter.
He said: “It’s going to be gossipy, light-hearted, chatty and irreverent but most of all fun, with lots of tea and cake.”
ITV bosses are hoping Antony will prove a teatime ratings hit as they have struggled to attract viewers after Paul O’Grady was poached by Channel 4.
An ITV source said: “Antony is shaping up to be a real viewers’ favourite. He’s definitely worth paying out the big bucks for.”
Last night Antony, right, told TV Biz: “I love Corrie and the viewers love Sean, so it’s all a dream come true.”
