This year's Billboard Hot 100 Fest is looking to be a must-buy ticket this summer if you're looking to see some great hip-hop acts, with some stacked headliners and even a mystery performer.

The headliners this year include Future, Rae Sremmurd, DJ Snake, and a mystery performer who, according to Complex, is a woman. 

Now, realistically, this mystery performer could be any female artist popular enough to fit a headliner slot at a big music festival like this. But if we apply a little logic, and a lot of faith, we can make some educated guesses. 

The first, and most obvious, choice would be none other than Cardi B. If we're talking about female artists who have exploded the Billboard Charts this year and last year, there's no better candidate. Not to mention that Invasion of Privacy just dropped, so a surprise Cardi announcement would generate a lot of hype for the festival. And while this may just be looking too deep into things, the space allocated for the surprise guest is just wide enough to fit Cardi B's name in there.

Another potential guest is Beyonce. She's come back to touring full force, and her and Jay Z will be performing in Buffalo, NY on August 18th as part of their On The Run II tour. The 18th is the first day of the festival, but it's not totally crazy to imagine her making her way to Long Island to headline the second day.

Other notable artists on the line up include Rich the Kid, Lil Xan, French Montana, MGK, Jacquees, and Bhad Bhabie. Check out the whole line-up below:
