They just celebrated their six year wedding anniversary.
So it's no wonder Nicole Richie and her husband Joel Madden were a little affectionate with each other as they got lunch to-go in Los Angeles on Monday, just one day after their big day.
The couple held hands as they strolled outside, both wearing head-to-toe black.
Joel, 37, meanwhile, wore a windbreaker vest, black T-shirt, hat, and sweatpants.
Just one day earlier, the rocker posted a sweet throwback photo of themselves in honour of their six year wedding anniversary.
The photo was of a violet-haired Nicole as she wore a pink flower crown beside her sharply dressed husband.
Joel captioned the photo, '(heart emoticon) 12-11-10 (heart emoticon).'
Together Nicole and Joel have two children - Harlow, aged eight, and Sparrow, aged seven.
In 2010 she told Oprah of the easiest and hardest aspects of her marriage: 'We met and we were partners from day one. And from the second we found out we were going to be parents together, we looked at each other and we said, "OK, both of our parents are divorced. We both have had ups and downs with our parents and we don't really have a strong example of what a healthy family life is."
'But we're recognizing that now, and so let's work at it, and let's go through this together as a team, and it's been great. And I would say that's the easiest and hardest part.'
