Congratulations to New Kids on the Block/NKOTBSB star Joey McIntyre on his ... New kid! McIntyre and his wife Barrett welcomed a baby girl, Kira Katherine McIntyre, yesterday afternoon.

Baby New Kid made her entrance at 12:30PM PST, weighing in at 7 lbs., 3 oz. and 21 in. According to the proud dad, she's "A beautiful baby girl with great timing and gorgeous hair."

Baby Kira is the first daughter for the couple, who have sons Griffin, 3, and Rhys, 1.

NKOTBSB -- the New Kids' collab with the Backstreet Boys -- made their 'Dancing With the Stars' debut back in April. On June 3, the boys, err, men will come together to rock the 'TODAY' show's Toyota Concert Series.
