Pregnant Fergie apparently feels a bit like she tripping, stumbling, flipping, and fumbling towards becoming a mom.

The pregnant pop star tells Good Morning America on March 21 that she's excited but apprehensive about becoming a first-time mom with hubby Josh Duhamel, according to Us Weekly.

"We're thrilled," the 37-year-old Black Eyed Peas singer says. "I know that my husband told everybody what I said. My quote when we found out — 'This blank just got real.'" 

"But it's true, when that moment occurs to you, there's going to be a human being growing inside of you... it's reality," she continues. "It's amazing, we're thrilled." 

Fergie says she's experienced a "little bit" or morning sickness but is now "feeling great." 

That said, she's aware that she has a lot to learn about being a mommy.

"I have no idea what I'm doing!" Fergie admitted. "I'm just going to play it by ear and see how things go, and let the natural instincts kick in." 

We gotta feeling she's gonna be a good mom.
