Singer/actor Donnie Wahlberg pulled out of a promotional appearance with his group New Kids On The Block in New York City on Tuesday (02Apr13) after filming over-ran on his hit U.S. Tv show Blue Bloods.

The boyband was forced to attend the album signing at music store J&R as a four-piece because Wahlberg was held up on set, but the star has promised to make it up to disappointed fans during the group's upcoming tour.

He first alerted followers to his potential no-show with a post on his page which read, "On set of Blue Bloods signing 500 pics (sic) in case they don't wrap me in time for J&R appearance tonight!"

Wahlberg later returned to the site to add, "Sorry to all at J&R Audio. Save your wristband & give them your email addy (address). You will get face time with me & Cd signed on tour in your city!

"Blue Bloods needs me today so I can be free for press tomorrow & Wednesday. So no in store for me. Hug & signed Cd guaranteed by summer end."
