Anyways, Bieber, Jenner, and Hadid stepped out for dinner at Alba in West Hollywood after celebrating the launch of Orebella's latest fragrance, Eternal Roots, earlier in the day. For the occasion, Hadid changed out of her white plunging Stella McCartney cowl-neck top into the evening's uniform: a black body-con dress and skinny nighttime shades.

Bieber was first snapped at Jenner’s birthday party wearing a white and red polka dot De La Val Gracia mini dress and what appeared to be a pair of Prada leather thong sandals as she sat on a bench on a patio holding a glass of red wine.

Kylie Jenner is celebrating another year around the sun! On Sunday, Aug. 10, the Kylie Cosmetics mogul marked her 28th birthday with a special dinner thrown by her sister Kendall Jenner, with close friend Hailey Bieber among the friends and family attending.
