Fergie and her husband Josh Duhamel drink "green goo" every morning.
Fergie
The 42-year-old singer and her 44-year-old actor have revealed they rustle up a home-made nutritious smoothie made from spinach, kale, celery, apple, banana and pears, every day, and they have been drinking the healthy juice for the past seven years to give them an energy boost to start their day.
Speaking about their daily routine, the 'Safe Haven' star said: "We drink green goo. But we call it green goo at our house.
"[Nutritionist] Kimberly [Snyder] introduced me to it on the set of the third 'Transformers' movie. It's spinach, kale, celery, apple, banana, pear - we've literally made it every day for the past seven years and it's just like energy in a glass."
And the couple have even tried "coaxing" their three-year-old son Axl into drinking it to help him have a higher intake of vegetables.
The dark-haired hunk said: "It used to take a little coaxing, but it's become a great way to make sure he gets enough greens."
Although the pair enjoy sharing the same breakfast starter together when it comes to working out they prefer to do their separate thing, although Josh has hinted he is envious of the 'Glamorous' hitmaker's "secret formula" when it comes to exercising.
He explained: "Hiking, that's our thing. We get outside together.
"We actually really like doing our own thing at the gym - but man, she has got some amazing secret formula that works. When she gets focused - like if she wants to get in shape for a specific event or something - give her just a few days and boom, she's done. I don't know how she does it. She's got it figured out."
However, Josh needs the encouragement of a personal trainer or a group leader to help him stay fit.
He told Health magazine: "I usually take some kind of a class, or I'm working out with my personal trainer. It just makes it easier. If I have somebody leading me and pushing me, I'll do it. If I just go to the gym alone, I do a couple arm curls and call it a day."
