Model Chrissy Teigen has just one rule for her musical husband John Legend when it comes times for them to have children: no hot nannies!

"No hot nannies, drivers or maids," Teigen told reporters at Lauren Conrad's New York Fashion Week show last Wednesday, according to Marie Claire. "It's an ongoing joke in my house. I do want to have 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.

"These days, it doesn't really matter what you look like - sometimes cabin fever just strikes and men do the do."

Teigen, 29, and Legend, 36, got married in Lake Como, Italy, in September 2013. Before they married they were engaged for two years and dated for four years before that, according to Billboard.

Teigen since tweeted an explanation about her hot nanny comment and said she was just joking.

"Just like low carb diet of licking chips, my 'no hot nannies' comment was a joke, clearly lost upon many. what is life. why must i type this," she wrote on Twitter. "I don't just go into random rants about hot nannies. The post asked, I jokingly answered. It isn't that f--king deep."

The model's comments about nannies were made just weeks after it was revealed that Ben Affleck reportedly engaged in a romantic relationship with his and his wife Jennifer Garner's nanny Christine Ouzounian. Affleck and Garner separated after 10 years of marriage.
