Glastonbury is returning to Worthy Farm after a fallow year, with Stormzy performing in the top slot on the Friday night.
Stormzy has performed at the festival before, on The Other Stage, but it's safe to say this will be the biggest performance of the grime artist's career so far.
That said not all festival-goers were impressed when he was announced as headliner, but Stormzy was quick to address his haters, saying people are "crazy" to think he'd ever perform a "mediocre" show at the festival.
He's clearly got big plans and, as he's known he'd be headlining since last year, he's likely had time to line up a few special guests to go on stage with him.
Here's some of the acts we think (and hope) might make an appearance on the Pyramid Stage.
Lily Allen
Lily Allen has been going to Glastonbury since she was a child, so we while she's not on the lineup this year we wouldn't be surprised if she's planning a visit to Pilton for the event.
The singer - who recently wowed crowds at Love Saves The Day in Bristol - teamed up with Stormzy on his song Cigarettes & Cush, which also featured Kehlani.
Wretch 32
Stormzy has teamed up with grime artist Wretch 32 on multiple occasions, including on his tracks 21 Gun Salute and a recording of Blinded By Your Grace Pt 2.
Wretch 32 doesn't have any gigs pencilled in until August this year - so if he's wanting a warmup Glastonbury could prove the perfect opportunity.

Jorja Smith
Jorja Smith has a stunning voice and features on Stormzy's track Let Me Down. The track was written by Jorja Smith and Stormzy and was released in January 2018.
Jorja already has her own set at Glastonbury - also on the Friday night, from 8.30pm to 9.30pm. If she were to perform with Stormzy it'd mean a quick sprint from West Holts to the Pyramid Stage, as he's on from 10.15-11.45pm.
Ed Sheeran
Arguably one of Britain's most famous songwriters, Ed Sheeran had his moment in the spotlight when he headlined Glastonbury in 2017.
He closed the Pyramid Stage at the festival, headlining on the Sunday night.
He teamed up with Stormzy to do a version of his track 'Shape Of You' and the pair performed together at the Brit Awards in 2017 - could they pair up again?
MoStack
MoStack is a rapper/artist from London who collaborated with Stormzy on Shine Girl. Stormzy's girlfrield Maya Jama - who grew up in Bristol - featured in the video.
MoStack released an album on June 7, so perhaps he'll bring some new music to a performance on the Pyramid Stage.
Sigrid
Stormzy is performing his biggest Belfast headline show to date at Belsonic on June 20 - and Sigrid has been announced as his special guest.
The Norwegian singer-songwriter is already performing at Glastonbury, on The Other Stage at 7pm on Saturday. She has no other tour dates around the festival - so she'd likely be able to make it to Worthy Farm early to see what it's like performing on the Pyramid Stage.
