Contrary to what Thomas Wolfe wrote, you can go home again. Just ask Joey McIntyre. The New Kid on the Block has been living in Los Angeles for several years, but he’s just bought a home on the South Shore. According to the Plymouth County Registry of Deeds, Joey Mac and his wife, Barrett, paid $450,000 for a place in Plymouth. No, the kid from Roslindale isn’t uprooting his family and moving back. “We’re firmly in LA — kids, school, career, etc. — but we found a little getaway in Plymouth,” McIntyre told us. “It’s nice to know my [three] kids will have a piece of Boston in their lives.” NKOTB, about to hit the road with 98 Degrees and Boyz II Men, will be at TD Garden May 30 for the One Fund Boston benefit.
