Backstreet Boy A.J. McLean Welcomes Baby Girl

Congratulations are in order for A.J. McLean and his wife Rochelle DeAnna McLean.

The Backstreet Boy, 39, and his wife of five years have welcomed their second child, daughter Lyric Dean. According to People, she was born on March 19, 2017 at 5:10 p.m. and weighed in at 8 pounds and 3 ounces. The little bundle of joy measured 22 inches in length.

McLean's oldest child, daughter Ava Jaymes, was born in November 2012.

The "I Want It That Way" singer revealed that he and his wife wanted to have another baby to give Ava a sibling–as well as, presumably, to enjoy that new-parent feeling. "I was told by someone very dear to me that having a child will change you forever, and that was beyond true with Ava," McLean said. "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," McLean, who has battled an addiction to alcohol, continued. "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."

McLean's wife reportedly went into labor during one of McLean's Backstreet Boys: Larger Than Life shows in Las Vegas on Saturday night. His Vegas residency will continue until July 1, 2017.

"Having two baby girls is a dream come true," McLean stated, "and we couldn't be any more proud or excited to welcome Lyric Dean McLean into the world and into our family."
