SNEAK PEEK: Newborn shoot of Iya and Drew Arellano's Baby Primo

Baby Primo, the firstborn of Drew Arellano and Iya Villania, is not even one month old yet, but he has become one of showbiz's most popular babies.

Thanks to his parents who have turned their Instagram feeds into an baby album of sorts!

Now 20 days old, Baby Primo, according to Drew, has "Papa's smirk."

Actually, he is the mini-me of his daddy, especially when he smiles.

Have you guys seen the behind-the-scene photos from his first pictorial courtesy of The Stork Studio?

At 10 days old, he's so maporma!
