Ben Affleck and Jennifer Garner
The 39-year-old actress – who is currently pregnant with the couple's third child – says the pair know they wouldn't be able to live without each other and know how important it is to show appreciation.

She said: "We both know we couldn't do what we do without each other. Ben always says, 'If you love it, we can make it happen.'

"He knows when to swoop in with the gesture. He's sweet that way. Honestly, I would do anything for that man, because I know it's not taken for granted."

Jennifer – who is already mother to Violet, six, and two-year-old Seraphina – also revealed how her third pregnancy is making her gain lots of weight because she is craving junk food.

She told America's InStyle magazine: "My kids had never seen Doritos before. They would say, 'Mom, where did you get that orange chip? I really want that.' I wish I was one of those cute pregnant girls who wear skinny jeans throughout their pregnancies. But I just gain weight."
