Lil' Kim will soon have a lil' person.

The 39-year-old rapper surprised onlookers Wednesday in New York City by appearing with a large baby bump during a New York fashion week event, according to the New York Daily News.

Wearing a skintight floor-length dress, Lil' Kim performed at The Blonds Fashion Week after-party, where she announced the big news.

"I'm a mom, but I can turn it up a little!" she said, touching her belly.

She later told Us Weekly, "I'm so excited! I'm a few months along, I can't wait to be a mom! I'm still going to work. I'm still going to be hard-core. The baby has made me even more of a beast."

Yeah, she'll be a beast ... at 3 a.m. when a screaming baby wakes her up for a diaper change.

Before her performance, she paid homage to late rapper Notorious B.I.G.

"It's also going to be Biggie's birthday and the anniversary of his death soon, so we (pointing to her belly) love you," she said to the crowd.

The rapper hasn't indicated who the father is.
