Jane Krakowski'30 Rock' star Jane Krakowski wants you clean out your closet.

The Emmy nominee, who stars in a new ad campaign for Tropicana Trop50, has teamed up with Tropicana and Dress for Success in an initiative called Girlfriends Giving Goodness.

"We thought it was a wonderful match up with Dress for Success for Girlfriend's Giving Goodness, girlfriends helping girlfriends. We all have so many clothes in our closet that we need to clean out and there are so many people in the world that need them," she explains to PopEater.

Krakowski, who donated a suit of her own, admires what Dress for Success does. "[It's] such a great organization that helps women get back on their feet."

During our chat, she also discussed a few upcoming episodes of '30 Rock,' and tells us to get ready for the live show, airing Oct. 16.

"All I have to say to tease you to tune in is: Tracy Morgan. Live show. Good luck." Watch Inside!
