Lily Allen and David Harbour control the apps on each other's phones.
The 39-year-old singer has revealed that she and her 'Stranger Things' star husband have come to an unorthodox arrangement to cut down on the amount of time they spend scrolling on social media.
Lily told The Sunday Times newspaper: "I now have a kids' phone called Pinwheel. It has no browsing capability and no social media, but you can still have Uber and Spotify.
"My husband is the caregiver on it, so he controls what I'm allowed to have as an app on my phone. I'm the controller of his as well."
The 'Smile' hitmaker explained that she laments how smartphones have "destroyed" humanity "as a species" and says the devices have had a grievous impact on her creativity.
Allen explained: "The creative side of my brain has been ruined by smartphones. I feel like everyone feels the same. I don't know anyone who can possibly say that the quality of their life is improved by the presence of a smartphone.
"I think it's destroyed us as a species. It's horrendous that they're designed to be so addictive. Some of us have more addictive personalities than others. It's evil."
Lily is also frustrated by the way in which social media can be used to punish comments that have been made in the distant past.
The star - who has daughters Ethel, 12, and Marnie, 11, with her former husband Sam Cooper - said: "It's unnatural. I don't think, as human beings, that you're meant to share ideas and for them to be set in stone. We are meant to evolve as people. How are you meant to do that if you're always held to account by things that you've said in the past?
"I said that 20 years ago, when I was completely different person, hadn't been married, hadn't had children. Of course I had a completely different outlook on life. Don't hold me to that."
