For fans who remember the days when a too-young-to-shave Joey McIntyre was the littlest New Kid on the Block, it might hardly seem possible that he’s a father — but McIntyre and his wife, Barrett, added a new member to their growing brood on May 31, and he used Twitter to share a snapshot over the weekend.

Introducing fans and followers to little Kira Katherine McIntyre with a “Happy Father’s Day : ) xoxo,” he went on to describe his new daughter as “a beautiful baby girl with great timing and gorgeous hair.”

McIntyre’s moment of domestic bliss comes in the midst of a joint tour and recording project between the New Kids and the Backstreet Boys, who have christened themselves NKOTBSB. The collaboration has produced a joint compilation CD which includes two new songs, ‘All in My Head’ and the first single, ‘Don’t Turn Out the Lights.’ The bands will be on the road across the US and Canada throughout the summer.
