Cypress Hill are reportedly supporting Rage Against The Machine at their Finsbury Park victory gig - Rage Factor - this summer.
Festival website efestivals is listing the rap collective as 'confirmed' on the line-up page for the June 6th free event.
Gallows have previously been officially confirmed as the official RATM support at their show at The O2 in Dublin two days after Finsbury Park, so it remains to be seen whether they're included on the London bill too.
Rage Against The Machine also headline Download Festival alongside the might of AC/DC and Aerosmith.
30 Seconds to Mars, Billy Idol, Stone Sour, Lamb of God, Deftones and Megadeth are amongst the smorgasbord of names ready to rock Donington Park as well.
