More babies on the brain?

Two months after welcoming her son David, singer Jennifer Hudson says she's already thinking about expanding her family.

"I'd like to have at least one more, a little girl," Hudson, 28, who is engaged to her son's father, David Otunga, tells Access Hollywood. "I want a girl and then maybe another one. You know, one baby at a time."

Of motherhood, the singer says it is a joy she's never before experienced.

"It of course is the most amazing thing ever," the singer says. "I love every minute of it."

What milestones has she most enjoyed sharing with her newborn? Little David has been "working on his smile and turning over," Hudson told Usmagazine.com at a Whitney Museum gala in New York City last month. "He really thinks he can talk! He really tries. No words come out, of course. He's like, 'Ahhh!' He says hi!"

The singer also tells Access that she finds the strength and inspiration to be a good parent when remembering her own mother, Darnell Donerson, who was tragically murdered along with Hudson's brother and nephew last year. (Hudson's estranged brother-in-law, William Balfour, has been charged with the killings.)

"[My mother] was the strongest person -- woman I've ever seen," says Hudson, adding that she "definitely" feels her mother's presence in her life. "Wherever, wherever. Every day, I'm like, 'Wow, I didn't realize I am so much like my mother until now."
