Jessica Simpson and her daughter are twinning in the star’s latest social media post.

The "Where You Are" singer, 40, took to social media on Thursday to share an adorable, makeup-free flick of her and her 1-year-old daughter, Birdie Mae.

"Tongue twister," Simpson captioned the clean-faced photo.

The duo is seen smiling at the camera with Birdie sticking her tongue out, while the mother-daughter pair's blonde hair shines bright in the flick.

"When I hear my kids cackle, it's the most healing sound," Simpson described. "It's contagious — my whole family starts giggling together, and it's like some form of happy laughing therapy."

Simpson revealed that after taking care of her kids -- who she shares with her husband Eric Johnson -- during the day, she journals every night.

"I started journaling after I wrote my book. It gets my thoughts out and lets me face them on paper. I know I can't carry the weight of the world and all those thoughts all the time," she said. "After a busy day of taking care of everyone, this clears my mind so I can have a restful night of sleep."
