Rebel Wilson's Pitch Perfect 4 hint that's got us believing it's happening!

Rebel Wilson and three of her Pitch Perfect castmates may have just given us a massive hint about a sequel...

Just like most fans, we thought the movie franchise had come to an end after Pitch Perfect 3, but Rebel has now posted a photobooth photo with Anna Camp, Brittany Snow, and Chrissie Fit, which we think is a massive clue!

She first posted a video of the girls in the photo booth, where you can hear them cheering- probably cause it's a cute pic, we've been there.

And then the following day- the photo itself.

It's seems like the typical photo of the cast members hanging out but if you look closer... The gals are pictured holding up four fingers- a subtle but SO obvious hint at Pitch Perfect 4, right?

Much of the cast and crew behind the movies have always said that they want the film franchise to continue.

When the cast appeared on The Ellen DeGeneres Show Anna Camp said she was in denial that the franchise could be ending, and Anna Kendrick assured fans that they would keep making the movies forever if they were given the opportunity.

Director Trish Sie also said: "I would see these movies on and on and on until they start sucking. I think whether it’s these women in the next stage of life or it’s a new group of women going through these things, I think there are endless ways to chart the course of the girls’ lives and a woman’s life."

Although everyone seems to be in for a new movie, there is still no official news about Pitch Perfect 4 yet. But, it's sounding good!
