Now his ex-girlfriend Megan Tomlin has spoken out about the allegations, saying the leak was nothing to do with her.
On the leaked audio, Dan can be heard abusively threatening another woman, believed to be Megan, telling her he would stab her if she slept with another man. The woman then retaliates by telling Dan, "You're having a baby with someone else."
Dan and his current girlfriend Jacqueline Jossa recently had a baby girl together – making it all the more likely that the recording is indeed of Dan and Megan.
However Megan has denied claims she was the one who handed over the recording.
"No, I didn't leak the tape. I'm looking into how it's got so much media attention. The police have it, obviously, and I have been accused of selling it. I didn't," she told The Mirror.
Far from trying to "destroy" Dan and Jacqueline's relationship by leaking the audio clip to the media, Megan insists she was the one who ended things with Dan.
"In the past 18 months, a lot of what's been written hasn't been based on fact,” she said.. "I'm not jealous and trying to split them up. I was the one who ended the relationship! I was happy telling him to go off and do what he's got to do.”
Although Dan has yet to be charged with any offence, he will not appear on TOWIE while the police investigation is ongoing.
