Want to have the best day ever?! Bumble and Barbieare teaming up to help.

The dating app is the latest to collaborate with Warner Bros. Pictures (in what is an increasingly long list) ahead of Greta Gerwig's upcoming film. The collaboration entails Bumble users getting words of encouragement from the film's Barbies and Kens, who will direct daters to use "Compliments", an in-app feature that helps people spark conversations.

The Bumble-version of Barbies and Kens will be around from today until July 26. From an initial glimpse, it seems the cast — including Margot Robbie, Ryan Gosling, Simu Liu, Issa Rae, and others — pop up with motivational pre-recorded messages and examples of positive reactions and compliments ("Your taste in movies? Sensational", "Your bio? chefs kiss"), then guiding users to send compliments to their potential matches.

"Barbies and Kens have a strong support system in each other," says Cameron Curtis, executive vice president of global digital marketing at Warner Bros. "We are excited to bring that to people on Bumble — and point to how this comes to life in Barbieon the big screen in theaters."

Bumble says that this creative overlap between the app and the film is helping to illustrate "the power of kindness", according to CEO Whitney Wolfe Herd.

"'Compliments' is just one of the many ways we empower our community to lead by example and make more meaningful first moves," says Herd. "We’ve seen this approach lead to a higher likelihood of matching and quality chats amongst our members, and we’ll continue to engineer kindness into everything we build."

So be like Barbie and her counterpart, and spread some positivity today. Online dating needs it.
