She welcomed her third child into the world two months ago.
And Jessica Simpson couldn't help but dote over her little bundle-of-joy on Saturday, sharing an adorable shot of a smiling Birdie Mae.
The 38-year-old took to her social media account to post a monochrome shot, calling her out for having the 'cutest dimples'.
'Cutest dimples I ever did see (said with some thick southern accent in my head),' she captioned, adding the hashtag, '#BIRDIEMAE.'
Birdie was seen in a woven seat while dressed in a onesie with a star design.
The two-month old, who was born on March 19, is the third child for Jessica and her former NFL husband, Eric Johnson - also raising daughter Maxwell, seven, and son Ace, five.
In some recent social media snaps, Jessica shared some tender moments of her kids spending time with their baby sister.
'I love the way she loves her,' she captioned a photo of Maxwell reading to Birdie, while she lay on a window seat cushion.
In a similar fashion, the singer captured Ace doting on Birdie too.
