Starting off her workday on a high note, Tina Fey was spotted filming scenes for "30 Rock" in New York City's Rockefeller center earlier today (October 5).

Showing off her musical prowess, the "Baby Mama" actress could be heard singing along with her iPod as she danced through the streets for what's sure to be one hilarious skit for the hit show.

In other news, the leading funny lady looks to be pulling in a massive amount of loot for her time on-air - tying "Desperate Housewives" star Eva Longoria on Forbes' list of highest paid television actresses.

While both Fey and Longoria earned themselves whopping $13 million between May 2011 and May 2011, stars like Marcia Cross, Mariska Hargitay of Marg Helgenberger didn't end up to bad themselves - making a cool $10 million each.

Enjoy the pictures of Tina Fey on the New York City set of "30 Rock" (October 5).
