Peter Andre said he is 'terrified' of his children being groomed online as he shared his support for a government campaign.
The Mysterious Girl singer discussed Nadine Dorries ' Online Safety Bill, which will protect children from harmful content such as pornography.
It will also limit people's exposure to illegal content and will protect freedom of speech.
Peter explained how he and the Secretary of State for Digital, Culture, and Media have worked together on the TV show called The Junk Food Experiment and stayed friends.
Writing in his column for OK!, the 49-year-old said: "Lots of people have asked me, 'Why do you let your children on social media?'
"But as a parent, it’s impossible to stop your children doing everything, so we need to have protective measures in place for when they are online so they are safe."
He explained how he already discussed online safety with his children Princess, 14, and Junior, 16 - who he shares with Katie Price - but he still 'worries' about it.
"Doing the campaign, I discovered that you can get devices now that change your voice, so a young girl might think they’re talking to a young boy, when really it’s an older man," he said.
"That terrified me and makes me worry about the future with Millie and Theo, too. Hopefully, through this campaign, we can make things safer."
The bill will require social media platforms, search engines and other websites to tackle illegal activity and uphold their stated terms and conditions.
Ofcom will also be able to fine the companies that fail to comply with the laws, make them improve their practices and block sites.

Peter shares Amelia, eight, and Theo, five, with his wife Emily MacDonagh.
The singer previously opened up about raising a family with no childcare can be 'full on', especially with how busy the parents can get.
Peter said he had been taking his children to various clubs, with him admitting in February that he had thought to himself: "I don't know how stay-at-home parents do it."
The star further commented: "Both Emily and I work and with no childcare, it can get full-on. I think there is often the view that it’s easy."
Earlier this year, he was able to be "a bit more hands-on" due to having time off work, with him managing to take over "a lot of the bits Emily would usually do" to give her a break.
The dad-of-four said: "She still shared some duties with me and it was unreal just how full-on it was. I honestly take my hat off to those who do it full-time."
