Looks like four is the perfect number for Ralph Lauren model Nacho Figueras and his wife Delfina Blaquier!

On Jan. 19 the couple welcomed their fourth child—baby girl Alba.

Delfina tweeted the exciting news and even shared a few sweet photos of her healthy, beautiful baby, which she captioned: "Alba Blaquier Figueras 19/1/13."

It's too bad Nacho, 35, couldn’t stick around to get to know Alba—the international polo star had to head out to St. Moritz for a polo event the very next day!

Before catching a plane, he lovingly sent out a Twitter photo of his new bundle of joy to all of his fans.

“The baby is due in January, but I hope the baby comes a little bit early! " Delfina told In Touch in October 2012. "Nacho named the first three children, but this time we both have some ideas about names.”

We wonder who picked this sweet moniker? Congrats to the happy couple on their new addition... she's adorable!
