London's Wireless Festival announced their lineup today. Sure, it features some pretty stellar acts: J. Cole, Post Malone, Lil Uzi Vert and more.

But, as pop songstress Lily Allen points out, there's one major problem: The three-day lineup only features three women in total.

Allen shared the festival admat featuring all the male acts whited out showing the three women included on the festival's lineup. The caption? "The struggle is real."

Of course, fans noticed the problem, too.

More acts are still to be announced for the festival, but fans are not happy with the lack of female artists so far.

Sadly, this isn't a new occurrence in the festival circuit. Last year, U.K.'s Reading & Leeds festival came under fire after announcing their first round of performers, containing 57 male performers and only one woman: Chrissy Costanza.

"I'm not gonna tiptoe around the issue, because I genuinely want the issue to be resolved, I want there to be change," Costanza said when we spoke to her last year. "If that means having to say the things that are a little bit more uncomfortable, then I'm willing to say that."

Earlier this year, Halsey called out Firefly festival for their lack of female representation, too. "Damn guys come onnnnnn. Where the women at. This was one of my favorite festivals I’ve ever played and it’s a shame there’s not more females on the bill. With the exception of (the amazing) Sza, the first like 20 acts on the bill are men. It’s 2018, do better!!!"

And we agree: It's 2018, and the music world can do better.
