Born last July, Jaime King’s son Leo Thames celebrated a very big milestone this weekend with his first birthday, and Mom (who has launched a gender-neutral kids’ clothing line) was kind enough to let the rest of us in on their special day, posting several sweet messages to social media.

First up? This shot of her gazing up at her adorably sad eldest, James Knight, as she holds baby Leo in her lap.

“HAPPY BIRTHDAY MY BEAUTIFUL BABY LEO THAMES! I can’t believe you are one today. My heart my miracle.”

She also helped another familiar face celebrate their milestone of one year as a Godmother: none other than Miss Taylor Swift.

Posting this super sweet collage of photos featuring Tay with the little tyke (some before he was ever even born!), she writes as follows:

“Wow @taylorswift13 LT’s first birthday already? He sends kisses and a bangin’ [two-teeth] smile to his Godmother in Oz. We heart you!”

Awwwww, how cute! Taylor, for her part, looks completely enamored with baby Leo as she gazes lovingly into his darling newborn face.

While the pop star has yet to publicly respond (she’s currently on set for Thor: Ragnorak with boyfriend Tom Hiddleston, as Chris Hemsworth recently confirmed), she did celebrate her Godson’s six month mark with this shot of the trio together back in January, saying, “LT is 6 months old today!”

She also posted one of the above collage photos of herself with the little guy, marveling at his rapid growth. “Pretty wild that 6 months ago, LT wasn’t even born and now he chews on my fingers.”

Pretty wild indeed, Tay! Congratulations to you both on your big milestones.

Are you surprised to see Taylor so at ease with this babe? Tell us over @BritandCo!
