Emma Roberts is expecting her first child with boyfriend Garrett Hedlund.

The actress confirmed her pregnancy with a photo posted to Instagram on Sunday. In the image, Roberts can be seen cradling her baby bump while wearing an ankle-length, polka-dot dress with puffy, off-the-shoulder sleeves. She wore no shoes or accessories with the dress, but did style her blonde hair in loose waves.

"Me...and my two favorite guys " she captioned the photo.

The Atlanta dress worn by Roberts in her Instagram photo was designed by clothing brand Sleeper. It's made from 100% linen, and retails for $320 at the time of writing. The dress is also sold in other colorways, including black, tan, and white with pink roses.

The garment could be considered a day gown or nap dress, which combines the leisure of pajamas with the elegance of evening wear, as Business Insider's Bethany Biron previously reported.

The Atlanta dress was "meant to be worn in the company of friends and loved ones," and "has a smocked bodice which allows you to wear it without a bra comfortably," according to its description on Sleeper's website.

Roberts has shown her affinity for the sleepwear brand's dresses in the past. On July 25, the "American Horror Story" star posted a photo of herself in the brand's Marquise linen dress.

The midi dress features a pink checkered print, corset-style bodice, and short, puffy sleeves. It retails for $203 at the time of writing.

Roberts has also documented a wide range of outfits she's worn while social distancing over the past few months. Back in April, she shared a photo of herself wearing a whimsical, pastel-colored dress from LoveShackFancy on her Instagram story.

More recently, she's worn an oversized white turtleneck, Fendi bathing suit, and a vibrant, yellow sweater.
