While Nelly's performance was as magnetic and polished as ever, fans had something else on their minds: Is it getting hot in here, or was it just Nelly's steamy performance? Twitter couldn't believe how good the rapper looked.

"so nelly gon be fine his whole life huh?" one fan tweeted. "Thank you Nelly for taking such great care of yourself. It's truly an honor to still be crushing on you 20 years later. Congrats sir," actress Lauren E. Banks tweeted. Some fans were just excited to be reminded of their own youth. "omgsh Nelly making me feel young again with this performance. I love this man!" one fan declared. We couldn't agree more.
