Chris Hemsworth's perfect response to his daughter saying she 'wants a penis'.

As anyone who follows Chris Hemsworth’s wife Elsa Patacky on Instagram knows, the Aussie actor is nailing the role of dad.

The Hemsworth-Patacky brood is now at three, and for the most part it seems like things are going pretty smoothly for the growing family.

“They get along, absolutely,” Hemsworth told Ellen of his four-year-old daughter India and his two-year-old twin boys Tristan and Sasha.

“Well, at times,” he clarified. Apparently, little India is a little “envious” of her baby brothers.

"She came to me the other day and she was like, ‘ya know, papa, I want one of those things that Sasha and Tristan have," Hemsworth said.

"I'm like, 'what do you mean?' She was like, 'ya know, the things in between the legs that you have.'

"And then my brain's like, eerrrrrr how do we handle this, you know?"

Somewhat flummoxed he gave explaining-gender-in-terms-a-four-year-old-might-grasp a go, but sadly hit a wall when he suggested India might grow breasts instead.

"I don’t want breasts," she said, clearly unimpressed. "She goes, 'I really want one.' I'm like, 'A penis?' And she's like, 'I want a penis!'"

Anyway, his eventual response was as perfect as you might expect.

"I was like ... 'Ya know what, you can be whatever you want to be.' And she goes, 'Thanks, dad!' runs off to the playground and that was it."
