Chrissy Teigen will never hire a ''hot nanny''.

While the 29-year-old model trusts her husband John Legend, 36, not to cheat on her, she admitted she will still make sure not to put any temptation in his way when they eventually have children.

She told PEOPLE: ''No hot nannies, drivers or maids. It's an ongoing joke in my house. I do want kids one day, so it's something that I have to think about.

''But the rule is no hot nannies. I trust John, but you never know with these men.''

However, Chrissy joked that she could already be in trouble as she currently has a ''hot assistant''.

She quipped: ''It's too late for me though, because I have a hot assistant - she is cute.

''These days, it doesn't really matter what you look like - sometimes cabin fever just strikes and men do the do. I have to keep an eye on my assistant.''

Chrissy may have to think about hiring a nanny sooner rather than later as she recently revealed that she is being pressured to have children by her family.

The Sports Illustrated model's relatives are desperate for her and John to welcome a new addition into the world.

She said: ''We've been together for so long at this point they've been begging for it since year two of our relationship. Of course we want to have kids.''

And the beauty has admitted everyone - family, friends and fans - will know about it straight away when she does get pregnant because she won't be able to keep it quiet.

She added: ''I won't be able to keep my mouth shut about it when it happens.

''We want a lot of kids. I would love to have three or four of my own, and then adopt a few. So basically I'll be pregnant the rest of my life.''
