'Teen Mom OG' Cast Member Gary Shirley Welcomes A Baby Girl

Find out how Amber Portwood's ex announced his little lady's arrival.

Gary Shirley is a father once more!

The "Teen Mom OG" cast member -- who is already a doting dad to six-year-old Leah with ex Amber Portwood -- just welcomed a daughter with longtime girlfriend Kristina.

"She's here!" Gary happily tweeted upon his gal's debut. And shortly after announcing that his precious princess arrived safely, G shared how he was bonding with his newest addition.

"Totally doing skin to skin!" he excitedly added.

No other details -- like the newborn's name or birth stats -- were revealed by the daddy of two, nor were any photographs posted. C'mon Gar, we want to peep your bundle of joy.

The Indiana native memorably discovered during this season of the docu-series that he and his ladylove were pregnant. And leading up to the kiddo joining the family fold, Gary took to Twitter to gush about his bundle of joy's around-the-corner entrance.

"Less than 1 week till I get to see my lil beauty! I'll have 2 then," the cookie connoisseur wrote at the end of April. And now, he does.
