Sean Strickland has not entered the octagon since defeating Paulo Costa via split decision in the co-main event of UFC 302 in June. 'Tarzan' appears set to receive the next opportunity to challenge Dricus du Plessis for the middleweight title. The No.1-ranked middleweight was recently called out by Machine Gun Kelly, who he has publicly criticized in the past.Speaking on the Impaulsive podcast, the musician and actor stated:"I don't know this guy from a crumb of bread. I didn't know who he was when I met him. I got hip afterwards that he's insanely racist and homophobic and just not my type of guy so I would've never even wanted to shake hands with him in the first place, but he also is just a representative of every person who's too scared to just be themselves because if you're comfortable as yourself, you don't care who anybody else is and how they are."'MGK' added:"He's so dumb that I'm going to tell him right now, you should not keep saying stuff because it just makes me look better, but you're going to keep saying stuff so I know that you'll react and say more things, but you just shouldn't. As a person who's just giving you big bro advice, learn this, shut the f**k up and don't speak on me anymore and live your life, but you won't and I'm going to continue laughing at you because you're a f**king idiot."Check out Machine Gun Kelly's comments on Sean Strickland below: Strickland was involved in an argument with Machine Gun Kelly at a Power Slap event earlier this year.
