Gwyneth Paltrow wishes her children could have had "super-cool" diapers.

The 'Contagion' star - who has children Apple, eight, and Moses, six, with husband Chris Martin - recently became enamoured when she saw a skull and crossbone-design on a baby and was shocked when she discovered they were created by her friend Jessica Alba.

Writing in her GOOP! newsletter, she said: "A few weeks ago, I saw a friend of mine's kid wearing these super-cool skull and bones diaper and I asked where they were from. It turns out they're from a brand founded by Jessica Alba and Christopher Gavigan.

"Not only are they incredibly cute, but they're also made from plant based materials, are completely non-toxic and are free from any harmful chemicals. I wish they'd been around when my kids were in diapers."

However upon exploring Jessica's brand further, Gwyneth - who has her own cookbook - discovered bath products she plans to use on her family.

She added: "I'm excited about their cleaning and bathing products and have already ordered a bundle myself."

Jessica set up the brand to help other parents find eco-friendly items for their children that were also "designed beautifully".

She told GOOP!: "I thought, 'Wouldn't it be great if there was one company I could get all my daily essentials from - from diapers to cleaning to bath time - and I could trust that they would be safe, eco-friendly, affordable and effective, as well as designed beautifully and delivered to my doorstep?'

"What a relief it would be for me, and many parents, to have this kind of resource! I wanted and desperately needed this kind of company - so I decided to work with Christopher to create an amazing experience."
