A.J. McLean has become a father for the second time.
The Backstreet Boys singer and his wife Rochelle welcomed daughter Lyric Dean - a sister for four-year-old Ava - into the world at 5.10pm on Sunday (19.03.17).
Lyric weighed in an 8lbz 3oz and measured 22 inches long.
A.J. said: ''Having two baby girls is a dream come true and we couldn't be any more proud or excited to welcome Lyric Dean McLean into the world and into our family.''
And little Ava is delighted to have a sister because she has spend months practicing for the arrival of her sibling.
A.J., 39, told People magazine: ''I was told by someone very dear to me that having a child will change you forever, and that was beyond true with Ava.
''We decided to try one more time because even though Ava is so independent, the idea of having a sister or brother for her became more and more important to us.
''Despite the fact that I'm an only child (and all jokes aside) turned out OK, my wife is one of four and that showed me there's something beyond special about having siblings. Now, seeing the excitement and anticipation that Ava has about being a big sister is truly amazing, and the best feeling in the world. She's been practicing for months with her dolls, and with some of my wife's friends' babies.''
Just a few weeks ago, the 'Larger Than Life' singer admitted he was concerned Rochelle would go into labour while he was performing with his group at The AXIS at Planet Hollywood Resort and Casino in Las Vegas - and she did just that on Saturday (18.03.17).
He said: ''God willing she doesn't go into labour while I'm doing the show. But if she does, I'll be on the first flight out right after the encore!''
