The insider tells PEOPLE that Hailey "loved having Justin there" to support her beauty brand's big international event

While Hailey Bieber's Rhode lipgloss-holding phone case was a hit, her new lipgloss-carrying belly chain is getting a mixed reaction.

Justin, Hailey, and their son, Jack Bieber, have been spending time in Europe as the family celebrates the release of his surprise album Swag. And the singer gave fans an intimate look at their trip on Instagram, notably sharing several new shots of baby Jack ahead of his first birthday next month.

Justin Bieber's new album SWAG dropped on Friday, and features multiple songs about his relationship with Hailey Bieber—including "Walking Away" and "Go Baby." And apparently the process of making the album brought Justin and Hailey closer together.

Hailey Bieber teased the launch of a new "lemontini" peptide lip tint with a photoshoot that included a gold belly chain. The beauty mogul founded rhode in 2022. The brand was recently acquired by e.l.f. in a "transformative" $1 billion deal.

Hailey Bieber offered her hot take on the butter yellow trend, calling the shade "played out." "It's not butter yellow because it's LEMON," the Rhode founder wrote in response to comments about her brand's latest lip launch.

The secret is to balance momentum with meaning. Every beauty founder dreams of accomplishing what Rhode just achieved: a billion-dollar valuation, a cultural following, and a brand that seems to dominate every platform it touches.

The limited-edition flavor follows the release of its six existing tints: Ribbon, Toast, Raspberry Jelly, Pbj and Espresso.

In a campaign to promote her new Lemontini Peptide Lip Tint Wednesday, Hailey Bieber posed in a black bikini accessorized with a custom gold belly chain adorned with the name of her billion-dollar beauty company.
