Singer Jennifer Hudson signs copies of her new book, "I Got This" at Barnes and Noble at the Grove on Jan. 12, 2012 in Los Angeles

*Jennifer Hudson is planning to wait a while before having another child, but says she desperately wants to give her two-year-old son, David Jr. a little sister.

“I want a little girl so bad! But not right now. Give it about three more years,” she says.

Despite her desire for a daughter, Jennifer admits David is the “sweetest thing” and has picked up traits from both herself and fiance David Otunga.

She added in an interview with ‘Access Hollywood’: “He’s always been such a good baby and he’s just the sweetest thing. He’s such a blessing. He’s very advanced for his age, so he likes to talk a lot. He’s a chatterbox. He loves to sing, he loves to wrestle. But he likes to wrestle mommy and sing to daddy!”

The Oscar-winning actress recently advised her ‘Dreamgirls’ co-star Beyonce Knowles to get as much sleep as she can while she gets used to being a new mother to week-old baby daughter Blue Ivy.

Jennifer said: “Girl, get your sleep! We talked about this when I had my munchkin. It goes so fast. She’s going to look up and Blue is going to be six months. Next thing you know, she’s going to be walking.”
