The photographs published at the weekend showed Walsh and Jones locking lips and dancing in the street on a night out, with an onlooker claiming they were "snogging like a pair of teenagers". "This is no excuse but it was a one-off drunken mistake which I am truly sorry for (sic)".
She wrote: "It's incredibly good of Sean (n) and Katya to apologise in the media".
It came after Seann and Katya both issued apologies to their Twitter accounts insisting it was an "one-off mistake".
'I have received nothing other than the support of my family, friends and a host of strangers on the internet who all wanted to make sure I was OK'.
She went on to clarify the narrative of the evening the couple were caught kissing: "Those pictures were taken on October 3rd". I was alone at home when Seann texted at 10pm, saying the two of them [he and Katya] were going for one innocent drink.
"We had spoken and I told him, not for the first time, that his actions over the past three weeks had led me to believe something inappropriate was going on".
She alleged: "He aggressively, and repeatedly, called me a psycho / nuts / mental".
Humphries since released a statement accusing him of "inappropriate", "hurtful" and "controlling" behaviour throughout their relationship.
After the snog made the front page of The Sun on Sunday, Walsh tweeted: 'In light of the story in today's newspaper I would like to offer my honest apologies for my actions.
Choosing to finally leave Seann, she continued with a plea to all women who are in similar relationships to her, 'This whole business has served to remind me that I am a strong, capable person who is now free; and no victim.
"I have a voice and will use it by saying this to any woman out there who deep down feels worthless and trapped with a man they love", she added. It's more than lying. 'What a powerful, important message, ' Stacey Solomon tweeted, 'You will help so many people going through similar experiences.
'Despite everything I hope he gets what he wants from this.
She revealed at the end of the note that she had moved out of their flat and taken their shared cat Winston with her.
