New dad Nick, who has recently released a solo lullaby album, was pictured alongside Drew, Justin Jeffre and Jeff Timmons on stage in Sunrise, Florida, on the weekend.
Last summer, Nick confirmed that 98 Degrees had reformed after 10 years apart and, although it was supposed to be a one-off, they started recording an album together in October.
The band are now on tour with Boyz II Men and New Kids On The Block and together they refer to themselves as "the dirty dozen" as a joke.
Speaking about his group's comeback, Nick recently said: "Music is very cyclical.
"You go through rock stages, R&B stages, rap stages… It's an uphill battle if you try and do pop during a rap stage."
They may be older and wiser than they were in their heyday, but we're glad to see them back together!
