In the post, Hailey, 27, was accompanied by her friend Hannah Cho as they spoke about a new Rhode product.
In contrast to her recent somber outings in Los Angeles, Hailey looked happy and animated as she tested her face wash and joked around with her pal.
The Victoria's Secret model looked super glamorous, with her shiny hair slicked back and a full face of makeup.
Hailey accessorized with plenty of jewelry, but ditched her classic "B" necklace. At one point, Stephen Baldwin's daughter danced happily as Hannah praised the new Rhode product, showing off her toned figure in a cropped hoodie and low-rise jeans.
Hailey's focus on her business comes amid speculation that her relationship is struggling.
Hailey and Justin Bieber, 29, celebrated their fifth wedding anniversary in September, but there have been rumors that their marriage is on the rocks.
Fans concluded she was planning to divorce Justin after noticing that she'd swept many of her old pics of him from social media. While fans spot social media "clues", an insider close to Hailey and Justin suggested that their relationship was in trouble.
"He acts like a needy kid all the time and she's constantly having to apologize for him and try to get him to act like an adult," a source told Radar.
The insider also claimed that Hailey is over Justin's "needy kid tendencies" and "immature behavior" after she was supposedly left mortified during an event the couple attended to promote a new drop for her skincare and makeup brand, Rhode.
