Ben Ofoedu says he's been 'trolled and abused' after cheating on his former partner, Vanessa Feltz.
The Phats & Small star, 50, admitted to sleeping with an older woman in Ibiza - as well as sexting others - leaving the TalkTV presenter, 61, 'heartbroken'.
Vanessa said her relationship was over following Ben's admission and now the singer claims to have received 'alarming levels of abuse' in the aftermath of their split.
He said: "It's been so hard. I've never been trolled before. I've never had the amount of abuse I've had, and I've never had people say the most horrible things."
Ben revealed he hasn't spoken to Vanessa since they split, but says he still has a 'lot of love' for her.
"I don't know what the future holds," he said. "I'm still very much in love with my fiancée. Of course I regret it, it's incredibly sad. I'm more heartbroken than anyone," reports Closer magazine.
Despite his 'heartbreak', Ben said he's being supported by his famous pals, including Boyzone's Shane Lynch, 5ives' Abz and Another Level's Dane Bowers.
Revealing the singers contact him "every day", he said he was "grateful" for their support.
Vanessa admitted she blindsided when she found about Ben's infidelity, but stressed there was 'no way back once the trust had gone'.
Thankfully, she's been a lot a brighter in recent weeks, including a cheeky admission in which she revealed she faked orgasms before her shock split.
Speaking on the Grazia Life Advice podcast, the former Celebrity Big Brother revealed: "I'm not saying do it every time but on those occasions – when you're not concentrating and thinking about defrosting the freezer and are never going to get there.
"You've got to fake it, it's only polite. Everyone saves face and no one's embarrassed or ashamed."
Following her split with Ben, Vanessa praised fans who have showered her with love and support as she opened up about celebrating her first birthday as a single woman.
Writing on her 61st birthday in her Yours magazine column, she said: "I've been showered with support and virtually hugged by thousands of lovely strangers.
"In the long, lonely hours when I have no hope of sleep, I read every single message and often reply, a stranger has thought to make time to reach out and hold me. I am touched to my very soul."
Vanessa is also being supported by her showbiz friends, including Lizzie Cundy, who reckons she's got a "list of toy boys lined up" for her friend, who she plans to "paint the town red" with soon.
