Pregnant Hailey Bieber's Growing Belly Peeks Out From Under Her T-Shirt in New Pic

Hailey Bieber is glowing and growing!

The model and mama-to-be, 27, shared a mirror selfie via her Instagram Story on Sunday, in which her baby bump peeked out from underneath a white T-shirt. Hailey and her 30-year-old husband, Justin Bieber , announced that they were expecting their first child together in May.

In the pic, Hailey casually wears a black blazer over a white T-shirt and jeans. She pairs the chic maternity look with gold earrings, black sunglasses, and a yellow bag. Her engagement ring is also now on her pinky instead of her ring finger.

Back in May, a rep told ET that Hailey was a little over six months pregnant at the time of her announcement. That means the Rhode founder's due date should land at the end of summer, potentially near her sixth wedding anniversary with Justin in September.

Last week, a source told ET how Hailey and Justin have been spending their time as they await their baby's arrival. In addition to "spending time with family and friends, going to church , and leaning on their close-knit circles on the regular," the two have "been trying to keep everything sacred during this special time."

The source emphasized that as the due date gets closer and closer, the couple's excitement about the next chapter in their lives grows.

"Justin and Hailey are feeling so thrilled and excited as Hailey gets closer to her due date. They can't wait to have a family together and are closer to one another than ever before," the source said. "They know that this was their destiny and that this chapter was what was in store for them and their partnership was meant to be."

Justin's also been one to oblige and cater to every one of his wife's needs.

"Justin has been doing little things to take care of Hailey whether it's satisfying her pregnancy cravings, massaging her feet, or treating her to nice dinners," the source said. "He's at her beck and call and the sky is the limit. Whatever she needs, he’s sure to get."
