No, it's not 1998 -- but last night, all four members of 98 Degrees reunited in Las Vegas, looking really well preserved!

Drew Lachey, Jeff Timmons, Justin Jeffre and Nick Lachey all met up for dinner at Nove Italiano inside the Palms Casino Resort on Wednesday night. And for the most part, they looked a lot like they did back their boy band heyday.

NSYNC, Backstreet Boys, Jonathan Taylor Thomas and more -- see how your other favorite 90s heartthrobs have held up through the years in the gallery above!

And take a trip back in time with the band's "Invisible Man" video below. Enjoy!
