And baby makes three kids on the block.
Joey McIntyre and his wife Barrett welcomed a baby girl Tuesday afternoon. "Kira Katherine McIntyre was born May 31st at 12:30 pm PST. 7 lbs., 3 oz., 21 in. A beautiful baby girl with great timing and gorgeous hair," McIntyre Tweeted
Kira Katherine joins big brothers Griffin Thomas, 3½, and Rhys Edward, 17 months.
McIntyre, 38, told PEOPLE in March that he wouldn't reveal the sex
of their new baby. But he let the secret out
in May, sharing the good news with NKOTB fans traveling with the band on their Carnival cruise.
The couple's son Rhys was born with severe hearing loss, and McIntyre has since gone public
with his family's journey to emphasize the importance of early diagnosis.
