Jenny McCarthy had the "birds and the bees" talk with her son because she worried he would develop a foot fetish

She explained: "I just had the birds and the bees talk...

"I kind of knew it was time because I accidentally told him that sex was like feet rubs. And I looked on his iPad and there were 2,000 pics of foot rubs and I'm like, 'Oh my god, he's going to have a foot fetish for the rest of his life!'

"So I just sat down and had the real heart-to-heart talk with him."

The former 'View' presenter - who is engaged to Donnie Wahlberg - admits it was "difficult" having the chat with her son, but she stuck to the basic facts and was happy to leave him "horrified" afterwards.

She added to Us Weekly magazine: "It was difficult ... but being the kind of single mom I've been, I've had to wear two hats and I'm proud to say that Evan will never be having sex for the rest of his life after my conversation.

"I talked about kind of the physical part. I'm like, 'You know how you're talking about things happening?' I'm like, 'This is what your body is going to want to do and it's normal but your body can't yet because you're too young,' and he was horrified, which is exactly what I wanted him to be but I can't even imagine."
