New Kids news

What’s old is new again. Just ask New Kids on the Block, whose compilation/collaboration CD with the Backstreet Boys is No. 7 on the Billboard 200. “Not bad for a bunch of old guys & old songs,’’ Donnie Wahlberg tweeted yesterday. The two bands will doubtless play cuts from “NKOTBSB’’ when they play the TD Garden Saturday and at Fenway on June 11. In other NKOTB news, Joey McIntyre and wife Barrett have a new baby girl. Kira Katherine McIntyre joins brothers Griffin and Rhys. And Jordan Knight celebrated the release of his new solo CD, “Unfinished,’’ with a gig at the Canal Room in NYC.
