If it looks like uber-publicist Lizzie Grubman is about to pop ... well, that's because she is about to pop.

TMZ spotted the pregnant PoweR Girl waddling through the streets of New York this week. Contrary to her headline-making incident in Hamptons a few years back, Lizzie managed this time to navigate her way around the city without taking out a giant group of bystanders.
