Benicio del Toro & Kimberly Stewart's baby's name is....

Benicio del Toro (44) and Kimberly Stewart (32), who insist they are not a couple, welcomed their first child on Sunday (which actually happens to be Kimberly's birthday too!), and they've released the name, Gorgeouses! Ready?

DELILAH!

Gorj! I love a good biblical name, you?

Kimberly's dad, Rod Stewart (66) -- who's loving being a grandfather for the first time -- revealed the name earlier today in an interview published in USA Today. "I'm a grandfather now," he told USA Today. "I've been going around blabbing that for hours now."

Love!
