But it didn't take Legend, real name John Stephens, to realise what he was missing and he left shortly after his performance making it home before 9pm – in time for Teigen's "short rib night".

The model and 10-time Grammy winner welcomed Miles on May 17, with Teigen taking to Instagram to share the first image of their baby boy shortly before the awards show kicked off.

Speaking to E! on the Billboards red carpet, Legend explained how they came up with his name:

"We named our first daughter Luna Simone Stephens; every name we give to our kids I think will have a little bit of musical history to it. So Miles is, of course, is the same name as the great Miles Davis," he said.

Teigen has been commended for not glossing over the realities of birth and motherhood with her 17.2 million Instagram followers and 10.6 million Twitter followers, even sharing an image of her in special post-birth underwear breastfeeding her son while Luna played nearby.

In another candid Twitter post, she added that giving birth the second time around was much less painful on her body than the first.
