A very pregnant Jessica Simpson, got a little mommy practice earlier this week.
The super smiley mommy to be was spotted carrying her nephew, Bronx Wentz, in New York City. Bronx's mom, and Jessica's younger sister Ashlee accompanied the duo as they made their way through the streets for a family fun day.
A very busty Jessica showed her pearly whites while her adorable little nephew hid his face, and beautiful blonde ringlets, under a black and white fedora -- quite a stylish little guy!
Bronx celebrated his third birthday last month and parents, Ashlee and ex, Pete Wentz, joined up to throw a birthday bash for their little boy.
We hope Aunt Jessica was taking notes. She'll be throwing birthday parties before she knows it!PHOTO:
