Want a Billie Eilish onesie for your baby? You're in luck...

Billie Eilish has launched a new children's clothing line, featuring socks (which are already sold out), onesies and more.

The mostly lime-green merch has arrived on her website under the moniker "Billie Eilish Kids", and it also features beanies and tees, with prices ranging from $20 to $60.

Have a look here.

Billie released her debut album 'When We All Fall Asleep, Where Do We Go?' earlier this year, and it'll see her tour the UK next July for a run that includes a ridiculous four shows at London's O2 Arena.

The details are:
