The 28-year-old American Horror Story actress took to her Instagram on Saturday (April 3) to share a sweet message in honor of Austen‘s 29th birthday.
“❤️👨👩👦❤️IT’S MY FAVORITE HOLIDAY O THE YEAR – @avstenrydell ‘s BIRTHDAY!!!” Billie wrote. “He’s the best best friend / the best dad / best person to wake up to (even when we’ve only slept 1 ish hours) / best adventure partner / best human in general WOWWWW I AM SO OBSESSED WITH HIM #sorryforthecaps #notreallytho #howelsecouldiexpressmyenthusiasum #DILF #waitno #DIDF and as frank sinatra says #youmakemefeelsoyoung !!!”
Along with the sweet message, Billie also shared a bunch of photos of Austen, while also sharing some rare photos of the couple’s son Kingston.
Billie and Austen surprised fans when they announced Kington‘s birth back in September 2020 after keeping her pregnancy a secret.
A few months ago, Billie revealed that she had a health scare while pregnant with Kingston.
