After 10 years, '00s boy band O-Town has announced their reunion.

Yesterday, the band announced their return via a video on YouTube.

"So it's official, after a 10 year hiatus O-Town are back!!! #OTown2014," the video's description reads. "'This one's for the fans and everyone who supported us from the beginning.' - O-Town"

Erik-Michael Estrada, Trevor Penick, Dan Miller and Jacob Underwood are all a part of the project, meaning Ashley Parker Angel is the only O-Town member missing.

"We started this reunion purely for the fun of it," Jacob told Billboard. "We had discussed a summer tour to perform our old songs and finally give the fans what they've been asking us for the last 10 years. However, once we began working, what developed was something a little more ambitious. The ideas kept flying, and we couldn't help but start making new music."

The band, which was formed in 2000 on the first season of reality show Making the Band (which was then on ABC) also relaunched their official website and updated their Twitter and Facebook pages.

"Each of us have different reasons for agreeing to do this again, a decade later," Erik explained. "Mine has to start with the fans. I never knew how much I would miss them. I never quite realized how much of an impact we had on them."

O-Town broke up after four years, two albums and a handful of hits including "Liquid Dreams" and "All or Nothing," which hit number 10 and number 3 on Billboard's Hot 100 chart, respectively, and "We Fit Together." According to Nielsen SoundScan, their first album sold 1.7 million copies and their second sold 257,000 copies.

"We are blessed to be able to apply what we've learned to create something stimulating and beautiful, that we can call ours," Underwood added. "This isn't just a reunion for us. It's a new beginning."

Meanwhile, Ashley will continue to do his own thing. He went solo in 2006 with a an MTV reality show and an album that sold 184,000 copies to date, according to Billboard. He's also been on Broadway and is "quite popular on social media," according to E! News.

The band will work without a manager or record label.
