"If the boy band thing is attached, it's wonderful, but for all of us in here, we're ready to get out there and sing and perform," he said. "That's just what we do."
Though 98 Degrees is the youngest group on the bill, it has been apart the longest, 12 years.
"So we're excited to get back together and doing what we do," member Nick Lachey said. "We feel reinvigorated by our bond and by our group, so we're very excited by that."
Wahlberg, who stars as Detective Danny Reagan on the CBS television series "Blue Bloods," about several generations of a family of New York City police officers, said the boy bands' tour, kicking off May 31 in Uncasville, Connecticut, and continuing into July with more than 30 dates, is going to be "great."
"You have three acts that have lots of records, lots of fans," he said. "Fans that are anxious to sing those records and anxious to sing other bands' records, too."
