A.J. McLean‘s situation just got “Larger Than Life” — he’s a dad again!
The Backstreet Boys member and his wife Rochelle welcomed their second daughter on Sunday, March 19, his rep confirms to PEOPLE exclusively. Born at 5:10 p.m. in Los Angeles, Lyric Dean McLean weighed in at 8 lbs., 3 oz. and measured 22 inches long.
Lyric joins big sister Ava Jaymes, 4.
“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,” McLean tells PEOPLE exclusively.
“Despite the fact that I’m an only child and (all jokes aside) turned out okay, 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.”
Adds McLean, “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.”

McLean hasn’t made it a secret that he hoped to add to his family. In January 2016, he spoke to PEOPLE about how the couple were exploring their options about whether they’d have a child biologically, adopt or make a different decision altogether.
But one thing’s for sure: He definitely knew having two kids wouldn’t be a cut-and-dry, been-there-done-that experience.
“Whatever our next child is, boy or girl, you would think that, ‘Oh I did it once, I’ve got it.’ No. It’s hard,” McLean said. “It’ll make it easier, but it’s still going to be a brand-new learning process.”
