AJ McLean's wife has ''baby fever'' again.
The Backstreet Boys star, who already has 23-month-old daughter Ava Jaymes with wife Rochelle DeAnna Karidis, has revealed they are planning to expand their family next spring.
The 36-year-old singer said: ''My wife's caught baby fever again so we're talking ... we're thinking number two. I leave on tour in April so we're thinking right around April we'll make a baby.''
The 'I Want It That Way' hitmaker is smitten with his little girl and claims she is very well-behaved.
He told PEOPLE.com at the Friends of Israel Defence Forces gala in Beverly Hills: ''Our daughter is the perfect girl. She lets you know when it's time to go to bed. She'll walk you upstairs, knock on her crib, let's go to bed. So, she's the best. She's the coolest kid.''
Ava is also showing signs of following in AJ's footsteps and is a huge fan of Rihanna.
He said: ''She's huge into dancing so we're about to get her into dance class. Not sure where she gets that from.
''We have a morning dance party.
''Right now she's on a Rihanna tip. So after breakfast she says, 'Riri,' that means Rihanna. And then 'moozik' instead of music and we put the iPad on and listen to Apple TV.''
