Lily Rose Cooper is this week enjoying becoming a mum for the second time, after giving birth to new daughter Marnie, but the youngster won't be alone in the celebrity offspring world - pop stars are squeezing out babies everywhere we look!

And they're not the only ones - the past year has seen celebrity babies popping out left, right and centre. It's been difficult to keep track and, although we do like the idea of an impending second generation supergroup, we've probably got a while to go before they start following in their parents' footsteps.

Having said that, let's not forget Blue Ivy Carter. Jay-Z and Beyonce's daughter had already featured on a Jay-Z track soon after she was born, with her cries ending the track. We don't see many of these other babies picking up a guitar though - and we're sure their parents will hear more than enough of their crying without adding it to a song.

So from hip-hop royalty to rock star children, we take a look at 15 of the babies that have already found a foothold in the music world.
