SI Swimsuit model Katie Austin has added a furry member to her family. She and her boyfriend, Lane Armstrong, are now parents to an adorable puppy.

The certified fitness trainer shared an adorable collage of photos featuring her new fur baby, Milly, on Instagram on March 19. If you thought things couldn’t get cuter, just wait. 

On Tuesday, Austin shared a precious video on the platform of herself working out, featuring Milly at her side every step and stretch of the way. The 2022 co-Rookie of the Year wore a baby blue athleisure set for her workout while Milly enthusiastically bounced around Austin’s yoga mat.

“how my at home workouts will look from now on… 1 week with Milly girl!!!” Austin gushed in her caption. “My little jumping jelly bean💗💗.”

At the end of the clip, the puppy grabbed Austin’s pink yoga mat in her teeth and started dragging it away, signaling the conclusion of the workout.

“This is the cutest thing I've ever seen,” Austin’s bestie and 2022 co-Rookie of the Year Christen Harper commented.

“She’s so dang cute,” wrote 2020 SI Swim Search winner Tanaye White.

“This is hilarious…,” Austin’s mother, fitness guru Denise Austin, added. “she’s sooooo cute….”

“Millie moving & burning those calories,” one person quipped.

“Awww 🤣 not pulling the yoga mat,” another follower pointed out.
