Many are calling the performance the ‘greatest of all time’, with Eminem performing alongside 50 Cent, Dr. Dre, Snoop Dogg, Kendrick Lamar and Mary J. Blige.

Footage of Bieber singing was shared to Twitter, with the caption, ‘Justin Bieber standing up and rapping to @eminem is a whole mood.”

In the clip, Bieber raps the lyrics, ‘He’s so mad, but he won’t give up that easy? No / He won’t have it, he knows his whole back’s to these ropes / It don’t matter, he’s dope, he knows that, but he’s broke / He’s so stagnant, he knows, when he goes back to this mobile home.’

Whlie most people loved it, some fans had mixed feelings about the clip. One wrote, ‘Sit down Justin. We don’t want to hear you try to rap.’

While others loved the video, saying ‘he genuinely loves eminem i love this lmaooo’.

Others shared Bieber’s enthusiasm and came out to say that Eminem’s performance along with Dr. Dre, Snoop Dogg, Kendrick Lamar, 50 Cent and Mary J. Blige, was the ‘GREATEST Super Bowl halftime show of ALL TIME’.

Prior to the show, the acts spoke about what an honour it was to perform on the iconic halftime spot.

Dr Dre said, ‘The opportunity to perform at the Super Bowl LVI half-time show, and to do it in my own back yard, will be one of the biggest thrills of my career.’

Snoop also spoke ahead of the show, saying, ‘For me, when performing, I never let the moment get bigger than me. I’m not going to understand it until it happens. While it’s happening, I’m in the zone. I’m stuck to the script, laser focused, being on point, sounding good, looking good and feeling good. I want to give off a great presentation. After the fact, it’s when I’ll be nervous about watching it to see what the reaction is. But while I’m going through it, it’s nothing.’

While Eminem also weighed in on the pre-show discussions, saying, ‘To me, there’s nothing more final than live TV,’ adding that it’s ‘f*cking nerve-wracking’.

Still though, the artists pulled it off and Bieber is firmly among those who loved it.
