The 38-year-old star has allowed her son Junior, 11, to join the photo sharing site after he bugged her for an account for three years but promises she'll be "keeping an eye" on his social media activity.

She wrote: "My baby boy has asked me for 3 years for Instagram so I've allowed it but I'm keeping my eye and have passwords (sic)"

And Junior used one of his first posts to show his mother he knew he needed to behave.

In a video posted to his page, he said: "Hi everyone, welcome to my Instagram page. I've been begging my mum for three years and now I have finally got Instagram. So I have to behave otherwise she'll take it off me!"

Since starting his page, Junior has been sharing pictures from his holiday.

And with Junior having his own account, Katie's nine-year-old daughter Princess - who she also has with ex-husband Peter Andre - has been "driving her mad" for an account but Katie promised she'll be "vetting" her daughter's posts too.

Taking to social media, Katie wrote: "Now my beautiful Princess has driven me mad for Instagram but I said I'll be vetting lol (sic)"

Princess posted a similar video message to her own account where she revealed her mother would have "full control" of her profile.

She shared: "Hi everyone, welcome to my Instagram. Junior had it and I really wanted it. I drove my mum mad, she let me have it and now she's in full control with me."
