Saturday, the New Kids on the Block came to Los Angeles as part of their summer tour accompanied by R&B darlings TLC and mega-hit rapper Nelly. The '80s/'90s boy band were minus one Knight brother, Jonathan, due to an “accident on the bus," according to his Twitter account. However, as the night proceeded, it was clear that although these men are definitely not new kids anymore—they still have the right stuff.

Here are five things we found pretty exciting while popping through the bubble of nostalgia also known as the Main Event.

1. Nelly has a shitload of hits.
First of all, Nelly is just as sexy as he was 15 years ago and has 21 million albums sold under his belt. Saturday, Nelly’s voice had a little more of a Ja Rule tinge than the higher octaves of his youth, but he still put on a helluva show. From “Country Grammar” to “Hot in Herre” to “Pimp Juice” to “Shake Ya Tailfeather,” the rapper brought back songs we didn’t even realize we knew the words to...and when we did realize it we couldn’t help but sing along with the rest of the crowd.

2. The choreography for "Waterfalls" is timeless.
We missed Lisa “Left-Eye” Lopes, but the two bookend members of the group, Tionne “T-Boz” Watkins and Rozonda “Chilli” Thomas, held it down. The duo brought on some intensely talented dancers to back up their performance, but in this moment, they didn’t need any fancy moves. The gentle, upper-body bounce from right to left with simple hand movements that's synonymous with the chorus brought us right back to 1995.

3. Space. Jumpsuits.
A lot of the dancers wore outfits we appreciated, with bootylicious shorts and tummy-loving crop-tops that allowed us to appreciate their movement. However, none of the crazy getups could top the iridescent, space-age jumpsuits that T-Boz and Chilli wore as they danced through the night. A perfect throwback to their '90s apparel.

4. Joey's abs are also timeless.
Despite having been doing this for more than 30 years, it didn't take long for the New Kids on the Block to prove to us that underneath those shirts, their abs are hangin' tough. The crowd made no secret of just how much they appreciated a peek at Joey McIntyre and his 42-year-old stomach. He is the youngest member of the group, after all. 

5. Women still love NKOTB.
The fan demographic of the night was across the board when it comes to R&B, rap and one of the original post-'60s boy bands. Needless to say, the average age was a leeetle higher than at a One Direction concert. However, by the screams and singalong choruses of the women in the crowd, you wouldn't have known the difference. These Blockheads don't seem to be going anywhere and the New Kids continue to blow their minds (sorry, couldn't help throwing one more in there).
