NEWS: Heidi Klum Talks Shielding Her Kids From Social Media: 'I Want to Keep Them Children as Long as Possible'

Despite being so open about her everyday life, the former Victoria's Secret model says she's a bit more over protective when it comes to her kids using social media.

"I am definitely one of them," she said during a recent interview "Live with Kelly and Ryan." "My oldest daughter [Leni] is 13 and she wants to post her face and I always say, 'No, you're not allowed to.' Whenever she's in it, it has to be from the back or [hiding her face]. It's different when we do it -- I feel like we're grown-ups -- but I want to try and keep them children as long as possible."
