Hailey Bieber's baby bump evolution: from barely-there to blossoming

Before announcing her pregnancy, Hailey kept her baby bump under wraps, coyly posing in oversized blazers to keep the news private.

Hailey and Justin finally shared their happy news on May 9^th, announcing their impending arrival via an artistically shot video of Hailey wearing a demure head-to-toe lade ensemble. The Rhode Beauty founder cradled her bump as Justin looked on proudly.

One week after her pregnancy announcement, Hailey proved she wasn't going to let a baby bump get in the way of her supermodel style, wearing a sensational beaded butterfly top that ensured her growing bump was centre stage.

Hailey proved that she rocks casual pregnancy style just as well as all-out glamour, baring her bump in an oversized white tee.
