Which Star's Kid Puts a Song in Our Hearts?

See if you can guess whose adorable daughter was spotted out and about L.A.

Every picture might tell a story, but not all of them can get us cooing.

Yep. This adorable shot of a certain rock 'n' roll legend's granddaughter definitely got the rhythm of our hearts beating like a drum.

And how could it not?

Seriously, just look at those cheeks!

So, just who is this young turk lady?

It's Kimberly Stewart's girl, Delilah!

The 5-month-old, whose daddy is actor Benicio Del Toro, was spotted in L.A. with her mommy on Monday.

The two gals later met up with Kimberly's mom (and grandpa Rod Stewart's ex) Alana for a little lunch followed by a short stroll.

Of course, it's only a matter of time before Delilah is enjoying playdates with dad-to-be Jack Osbourne's kid!
