Actress Mila Kunis is shooting the final scenes of her upcoming movie Bad Moms, which will release in mid-2016. And Mila’s new movie has just surprised us all with a new addition to its cast that’s just been revealed on social media—it’s YouTube sensation Lilly Singh, who’s better known to her legion of fans as Superwoman (her YouTube alter ego). Singh has confirmed that she’ll be doing a hilarious cameo in Bad Moms.

The surprising news got out when Lily Singh shared a photo on Instagram of her posing with Mila Kunis on the streets of what looks like the movie’s set. Lily captioned the picture with, “SURPRISE! I have a small cameo in the new Mila Kunis/Christina Applegate movie called #BadMoms.” She goes on to talk about how much fun she had on the sets with Mila Kunis and co-star Christina Applegate, and how kind they were in real life: “And can I just say, it was SO extremely wonderful to witness the amount of #GirlLove on this set. Mila and Christina were both so welcoming and kind to not only myself but everyone else on set,” wrote Singh.

The funny video blogger clearly joined the Bad Moms cast around Valentine’s Day, considering how she shared her first meeting with the leading ladies: “In fact, when I first met Mila, she was handing out Valentine’s Cards to everyone. Moments before that, Christina was sending care packages to a few of the ladies who were sick on set. [sic]” Singh went on to thank them for being so humble and “awesome as eff,” and also coined Mila Kunis and Christina Applegate as being “hot as hell.” No doubt about that!

The stunning Mila Kunis will be returning to the big screen as, of course, a mother in the upcoming comedy Bad Moms. The movie is produced by Judd Apatow’s Appatow Productions and Merced Media, and is directed by The Hangover screenwriters Jon Lucas and Scott Moore. The movie stars Kunis, along with Christina Applegate, Kristen Bell, Kathryn Hahn, Jada Pinkett-Smith, and, of course, Lilly Singh.

For those who aren’t familiar with Lilly Singh, the comedian shot to fame with her hilarious skits and inspirational talks as “Superwoman” on her YouTube channel. The Superwoman channel has garnered over a billion views and brought in millions of subscribers. Singh, who just wrapped up an international tour and is now promoting her new online movie A Trip to Unicorn Island, adjusted her packed schedule for this cameo in Bad Moms, which was worth it, because it has officially gotten her into a mainstream Hollywood flick.

So, be sure to catch Lily Singh, Mila Kunis, and the rest of the A-list cast when Bad Moms hits cinemas on August 19, 2016.
