Heidi Pratt's older sister captioned the snap: "Super ninja baby!" as she shared the first photo of her baby boy.
Dressed in an adorable stripey orange and white baby-gro and spread out on a quilted throw, Isaiah looked a little puzzled. But then again, the world is a very confusing place when you're only three weeks old!
Isaiah Hawk was born on Sunday, 3 May, weighing 7lbs 5oz. Aunt Heidi tweeted her excitement about her first nephew's arrival, saying: "Congratulations to my sister @hollymontag and @wichierilson on their new baby boy, Isaiah Hawk Wilson! #Blessed Can't wait to meet him!"
The former Hills star is no doubt besotted with Isaiah, Heidi has made no secret of the fact she'd also like to start a family. She's been married to The Hills co-star Spencer Pratt for six years, and wants kids now. Spencer recently did a u-turn and revealed he'd also like a family with Heidi, after being firmly against the idea for years!
A few days after Isaiah's birth, Holly gushed on Twitter: "I have never been more in love @wichierilson and I are beyond blessed that our angel Isaiah chose us to be his parents. Thanks for the love!"
Holly announced her pregnancy over Christmas, just a few months after she married boyfriend Richie Wilson in a fairytale ceremony in her Crested Butte, Colorado hometown.
