Did We Know Lizzie Grubman was Pregnant?

I didn't know Lizzie Grubman was pregnant. How can the maven of celebrity publicity not get the word out about her own pregnancy?

Well, she had a baby and it's a boy named Harrison Irving Stern, according to People magazine. Grubman, 35, and her advertising executive husband Chris Stern,36, welcomed Harrison on Tuesday morning in New York City. Grubman and Stern were married in March of this year and this is the first child for both.

If you don't know Lizzie from her representation of clients like Britney Spears and Diddy, you may know her from her MTV reality series Power Girls. The show followed Grubman and her staff as they worked their magic in New York City.
