The “I Want It That Way” crooner and his 34-year-old hairstylist/make-up artist wife, Rochelle, are already parents to three-year-old daughter Ava – the only girl in the Backstreet baby family, which includes Nick Carter’s 4-month-old son Odin, Brian Littrell's 13-year-old son Baylee and two boys each for Kevin Richardson and Howie Dorough.
While she may be the only girl, adorable Ava is already following in her boy band dad’s footsteps by showing musical genes on a daily basis.
“She’s a huge fan of music and she just kills me,” McLean tells ET. “Everyday Rochelle sends me a brand new video of Ava singing something acapella or to a track and I’m just like, ‘Oh my gosh. She’s me.’ It’s crazy!”
The baby news comes amid a busy time for the Dead 7 star.
As well as preparing to release his solo record Naked, McLean is also recording new Backstreet Boys music, preparing for the band’s 2017 Las Vegas residency and getting ready to play the lead character in an upcoming project from horror director Eli Roth.
