Nick Lachey, brother Drew, Jeff Timmons and Jeff Jeffre reunited this morning on "Today" -- performing for the first time together in 10 years as 98 Degrees.
Instead of going shirtless and showing off their matching tattoos, the boy band covered up in matching black outfits to perform four of their hits: "Because Of You," "I Do," "Invisible Man" and "Hardest Thing."
No surprisingly, the audience was mainly made up of 20-30 something females ... who were singing along with every word.
"It's great to be back together and do what we love to do together on stage," Nick Lachey said.
Drew added "There's back pain, throat pain, knee pain, ankle pain, hip pain. Our menu went from like steak and lobster to Metamucil and prune juice."
The boys will also hit the stage together this weekend in Hershey, PA for the MixTape Festival -- where other boy bands Backstreet Boys and New Kids on the Block will also perform.
