The 35-year-old actress married John back in 2010 and the couple have two young daughters together - four-year-old Hazel and 20-month-old Violet - but although she'd like to be the kids' favourite, they tell her that daddy is the best.

Speaking to 'Entertainment Tonight', Emily said: "They like John even more than me, which is slightly upsetting at times.

"When I ask the little one, like, 'Who is your best friend?' She's like, 'Daddy.' "

Emily also revealed how her daughters are both terrible at keeping secrets when it comes to birthday, Christmas or Mother's Day surprises.

She said: "Mother's Day and any birthday in my house, is kind of funny because my kids are terrible at keeping surprises, especially the older one. She's like, 'Mommy, I got you that pink scarf you loved.' And John's like, 'No!' It'll usually be then the surprise will get busted, but they're so sweet."

Emily and John will be seen in their first movie together this month when horror film 'A Quiet Place' - which John also directed - hits cinemas.

And John, 38, has nothing but praise for his wife after seeing her acting talents from behind the camera for the first time.

He said: "I think because we're both actors, people think we have the same experiences but we have a completely different experiences. She's off working with a different crew, cast, director and I usually do my own thing.

"So, to actually see what it is that makes her such an amazing actress, I've obviously been the biggest fan of hers forever, but to see her on set doing what she does, when you're in the room it's a whole different thing."

And Emily responded by saying they have always been "great partners in life" and the movie helped them bond in a way that they had never done before.

She said: "We've always been great partners in life, but I think professionally we'd never had that experience.

"And ultimately because the movie means so much to us and seeing each other in a professional realm and also allowing that sort of new side that we saw in each other was really bonding, it was like very cool."
