Gwyneth Paltrow, Erin Foster and Sara Foster joined Whitney Wolfe Herd, the founder and CEO of Bumble, to launch a new app feature, Bumble Bizz, in Los Angeles earlier this week.

On Nov. 16, a press release revealed that the three women were joined by countless other big-name celebrities at the event, including Kim Kardashian West, Goldie Hawn, Courteney Cox, Jennifer Garner, Molly Sims, Jennifer Meyer, Estelle, Leslie Mann, Judd Apatow, Katherine McPhee, and David Foster.

As Enstars previously reported, Erin and Sara Foster were named as the Heads of Creative for Bumble Bizz and Bumble BFF weeks ago.

Bumble is a female-driven social networking app that recently debuted Bumble Bizz, which offers users a safe and friendly way to make professional connections with one another by mentoring others and furthering their careers. As some may recall, the app was initially launched as a dating platform and currently boasts over 23 million users worldwide.

The Bumble Bizz launch event was held on Nov. 15 at Iron Chef Nobu Matsuhisa's beachfront restaurant, Nobu, and included a cocktail hour, dinner, and an after party.

The Bumble Bizz featured on the Bumble app instantly connects users by enabling them to swipe through people nearby who are looking to network, connect, and mentor, just as the dating feature and the Bumble BFF feature of the platform.

When the reality star daughters of music producer David Foster were first tied to the app, Bumble CEO Whitney Wolfe Herd released a statement.

“Erin and Sara are true forces of nature and have already brought so much value to our brand and our culture,” she said. “The work we’re doing together will have such a positive impact on our overall user experience and give our brand a powerful new voice.”

At the same time that the Foster sisters were announced as creative heads of the app, they spoke out about their new project with Bumble and it's exciting new features. In Erin's message, she pointed out that there has never been a better time to launch a platform for women to support one another in the business world.

“Erin and I have admired Bumble and Whitney’s vision for equality since the brand launched,” Sara added in a statement of her own. “We’re honored to join forces to support the idea of building supportive networks through friendship and professional connections.”
