The Dorchester-reproduced New Kids on the Block part turned 50 on Saturday.
Donnie Wahlberg turned 50 - or "40 again for the tenth time," as the performer/entertainer put it - on Saturday.
Also, to commend the event, everybody from Wahlberg's New Kids on the Block bandmates to his better half Jenny McCarthy ringed in to send birthday wishes.
The hashtags #HappyBirthdayDonnie and #BHLove (alluding to Blockheads, the authority moniker given to NKOB super-fans) were in any event, moving on Twitter.
Official records for NKOB and Wahlberg's CBS series "Persons of nobility" posted accolades.
His sibling, entertainer Mark Wahlberg, went old-school with his holler to the "huge brother," posting a legacy photograph of the pair with subtitle
We have made considerable progress since this photograph - wouldn't be where I am today without you!"
NKOB part Danny Wood tweeted that Wahlberg was his "deep rooted" dearest companion,
sharing photographs of the pair in front of an audience performing together. "Appreciate #50," he composed.
