Grimes has been celebrating her first Mother's Day as a new mum, and marked the occasion by sharing rare footage of partner Elon Musk cuddling their brand new baby son.
The little boy - who they've named X Æ A-12 - was seen curled up on his dad's chest as Elon gently patted his back to wind him.
Tiny X Æ A-12 seemed to be rocking off to sleep in the intimate footage, which Grimes captioned with a simple pink love heart.
It comes after the happy couple announced the reasons behind their unusual name - although Elon had to correct his girlfriend when she got part of the moniker wrong.
