Miranda Kerr reveals the secret to her strong and happy marriage to Snapchat ... trends now

Supermodel Miranda Kerr has shared intimate secrets about her happy marriage to tech billionaire Evan Spiegel.

Since the pair lead such high-speed lives, the 40-year-old businesswoman and mother of four said it was important to keep the romance alive with regular 'date nights'.

Miranda, who welcomed her fourth child - son Pierre Kerr Spiegel in February - added it was also important to set aside some 'alone time' every day. 

Speaking to 9Honey Celebrity, the entrepreneur and former Victoria Secret model also said it helped that both she and husband Evan, 33, were early risers.

The former Victoria's Secret model said she wakes up as early as 5.30am to enjoy time to her self. 

'At the moment, because I'm six weeks postpartum, I'll end up just doing like a meditation. But prior to that, that's when I would do my yoga workout or something before the kids were up.

'So having that time really gives back to myself, so I feel like my cup is full before any of the kids are even up.'

Miranda also shared that 'private time' with Evan was a priority and not just on date nights but also at he end of every day.
